feat: add daily note command — Cmd+J creates or opens today's journal note (#168)

* feat: add daily note command — Cmd+J creates or opens today's journal note

Adds "Open Today's Note" command accessible via:
- Keyboard shortcut: Cmd+J
- Command Palette (Cmd+K → "Open Today's Note")
- File menu bar entry

If journal/YYYY-MM-DD.md exists, opens it. Otherwise creates it with
Journal type frontmatter and Intentions/Reflections template sections.

Also refactors useNoteActions to extract a shared persistNew callback,
reducing code duplication and keeping CodeScene complexity thresholds green.

+# Drag & Drop Images — Implementation Summary
 
-## Summary
+## Problem
+Dragging image files from Finder into the BlockNote editor didn't work. Tauri v2's
+`dragDropEnabled` defaults to `true`, which intercepts OS-level file drops before they
+reach the webview's HTML5 DnD API — BlockNote never received the dropped files.
 
-Refactored three CodeScene hotspot files to improve code health scores:
+## Solution
+Instead of disabling Tauri's drag interception, we use Tauri's `onDragDropEvent` API
+to listen for native file drops and handle them directly:
 
-| File | Before | After | Approach |
-|------|--------|-------|----------|
-| Editor.tsx | 7.82 (cc=35) | 10.0 | Decomposed into EditorContent, EditorRightPanel, SingleEditorView, editorSchema, useDiffMode, useEditorFocus, suggestionEnrichment |
-| NoteList.tsx | 9.04 (cc=13) | 9.38 | Extracted createNoteStatusResolver, toggleSetMember standalone functions |
-| Sidebar.tsx | 9.09 (cc=10) | 10.0 | Extracted applyCustomization standalone function |
+1. **Rust backend** (`src-tauri/src/vault/image.rs`):
+   - Added `copy_image_to_vault` command that copies a file by OS path into
+     `vault/attachments/` with a timestamp-prefixed filename
+   - Refactored shared path logic into `prepare_attachment_path` helper
+   - Validates file exists and has an image extension before copying
 
-## New files
+2. **Frontend** (`src/hooks/useImageDrop.ts`):
+   - Added Tauri `onDragDropEvent` listener that fires on native OS drag-drop
+   - On `drop`: filters for image paths, copies each to vault, calls `onImageUrl`
+   - On `over`: shows drag overlay (paths aren't available until drop)
+   - `copyImageToVault` invokes the new Rust command and returns an asset URL
 
-- `src/components/EditorContent.tsx` — breadcrumb bar + editor/diff view switching
-- `src/components/EditorRightPanel.tsx` — AI chat / inspector panel toggle
-- `src/components/SingleEditorView.tsx` — BlockNote editor with suggestion menus
-- `src/components/editorSchema.tsx` — WikiLink inline content spec + BlockNote schema
-- `src/hooks/useDiffMode.ts` — diff mode state management
-- `src/hooks/useEditorFocus.ts` — editor focus on custom event
-- `src/utils/suggestionEnrichment.ts` — shared suggestion item enrichment pipeline
+3. **Editor integration** (`src/components/SingleEditorView.tsx`):
+   - `useInsertImageCallback` inserts a BlockNote image block at cursor position
+   - Wired into `useImageDrop` via the `onImageUrl` callback
+   - `vaultPath` threaded through Editor → EditorContent → SingleEditorView
 
-## New tests (20 tests)
+4. **Existing `/image` slash command** continues to work unchanged (uses `uploadFile`
+   on `useCreateBlockNote` → `uploadImageFile` → `save_image` Tauri command).
 
-- `src/hooks/useDiffMode.test.ts` — 10 tests
-- `src/hooks/useEditorFocus.test.ts` — 3 tests

+Every feature must be reachable via keyboard. This is both a UX requirement and a QA requirement — Brian tests the native app using keyboard only (osascript key events, no mouse).
+
+**Before marking any task done:**
+- Can the feature be triggered/used without touching the mouse?
+- If it requires clicking a button, add a command palette entry or keyboard shortcut
+- Document the shortcut in the command palette or menu bar
+

+# Laputa — Vision
+
+Laputa is a personal knowledge base where humans and AI agents collaborate as equals.
+
+---
+
+## Core principles
+
+### 1. The vault is the source of truth
+Everything lives in the vault as plain text files. Notes, relations, configuration, instructions — all Markdown with YAML frontmatter. No proprietary database, no hidden state. If you can open a terminal, you can read your vault. If you can write Markdown, you can modify it.
+
+### 2. Vault-native configuration
+Laputa configures itself through files inside the vault — the same files you write and read every day. There is no separate "settings app" or admin panel. If you want to change a theme, you edit a note. If you want to give instructions to an AI agent, you write a note. If you want to define a template, you create a note.
+
+This applies to:
+- **`_themes/`** — themes as notes with a YAML block in the body. Edit `_themes/dark.md`, see the colors change in real time.
+- **`AGENTS.md`** — instructions for AI agents. Write what you want them to know about your vault in plain language. They read it before acting.
+- **`_templates/`** — note templates per type. Create `_templates/event.md` and every new event starts from that structure.
+- **`_procedures/`** — recurring tasks as notes with a `schedule` frontmatter field.
+
+The principle: **if it can be expressed in frontmatter + Markdown, it doesn't need a UI**.
+
+### 3. Structure through types, not folders
+Notes have a `type` field. Types determine folders, icons, and colors — but the structure is defined by the data, not the filesystem hierarchy. You can query "all events in February" without knowing anything about folder layout.
+
+Relations between notes are expressed as frontmatter arrays: `people: [Marco, Sara]`. A wikilink `[[Marco]]` in the body navigates to the person note. The graph emerges from the data, not from a separate graph database.
+
+### 4. The file is the interface
+You can use Laputa's UI, or you can open a terminal. Or a text editor. Or Claude Code. They all operate on the same files. There is no difference between "the app" and "the vault" — the vault is the app.
+
+This is why Laputa has an MCP server: external agents get the same tools the in-app AI panel uses. The interface is a convenience, not a requirement.
+
+### 5. Humans and AI as collaborators
+Pulse — the activity feed — shows the history of the vault without distinguishing between human commits and agent commits. That's intentional. Laputa is designed to be a space where you and your AI agents work together, each contributing to the same knowledge base.
+
+The AI doesn't have a separate workspace. It works in yours.
+
+---
+
+## What Laputa is not
+
+- Not a todo app (though you can use it as one)
+- Not a note-taking app that syncs to the cloud (the vault is yours, sync however you want — git, iCloud, rsync)
+- Not a replacement for a terminal (power users will use both)
+- Not trying to abstract away git (git is a feature, not an implementation detail)
+
+---
+
+## The long game
+
+A vault that grows with you for years. Events, people, projects, thoughts — all interconnected, all version-controlled, all accessible to any tool that can read a file.
+
+Ten years from now, your vault should still be readable. Plain text is forever.

+The MCP server (`mcp-server/`) exposes vault operations as tools for AI assistants (Claude Code, Cursor, or any MCP-compatible client).
 
-| Tool | Description |
-|------|-------------|
-| `open_note` | Open and read a note by path |
-| `read_note` | Read note content (alias) |
-| `create_note` | Create new note with frontmatter |
-| `search_notes` | Search by title or content |
-| `append_to_note` | Append text to a note |
+#### Tool Surface (14 tools)
 
-**Transports:**
-- **stdio** — standard MCP transport (`node mcp-server/index.js`)
-- **WebSocket** — live bridge for app integration (`node mcp-server/ws-bridge.js`, port 9710)
+| Tool | Params | Description |
+|------|--------|-------------|
+| `open_note` | `path` | Open and read a note by relative path |
+| `read_note` | `path` | Read note content (alias for `open_note`) |
+| `create_note` | `path, title, [is_a]` | Create new note with title and optional type frontmatter |
+| `search_notes` | `query, [limit]` | Search notes by title or content substring |
+| `append_to_note` | `path, text` | Append text to end of existing note |
+| `edit_note_frontmatter` | `path, patch` | Merge key-value patch into YAML frontmatter |
+| `delete_note` | `path` | Delete a note file from the vault |
+| `link_notes` | `source_path, property, target_title` | Add a target to an array property in frontmatter |
+| `list_notes` | `[type_filter], [sort]` | List all notes, optionally filtered by type |
+| `vault_context` | — | Get vault summary: entity types + 20 recent notes |
+| `ui_open_note` | `path` | Open a note in the Laputa UI editor |
+| `ui_open_tab` | `path` | Open a note in a new UI tab |
+| `ui_highlight` | `element, [path]` | Highlight a UI element (editor, tab, properties, notelist) |
+| `ui_set_filter` | `type` | Set the sidebar filter to a specific type |
+
+#### Transports
+
+- **stdio** — standard MCP transport for Claude Code / Cursor (`node mcp-server/index.js`)
+- **WebSocket** — live bridge for Laputa app integration:
+  - Port **9710**: Tool bridge — AI/Claude clients call vault tools here
+  - Port **9711**: UI bridge — Frontend listens for UI action broadcasts from MCP tools
+
+#### Auto-Registration
+
+On app startup, Laputa automatically registers itself as an MCP server in:
+- `~/.claude/mcp.json` (Claude Code)
+- `~/.cursor/mcp.json` (Cursor)
+
+The registration is non-destructive (additive — preserves other MCP servers) and uses `upsert` semantics. The entry points to `mcp-server/index.js` with the active vault path as `VAULT_PATH` env var.
+
+Registration also runs from the frontend via the `useMcpRegistration` hook and `register_mcp_tools` Tauri command, ensuring the config stays up-to-date when the vault path changes.

+### Rust MCP Module
+
+`src-tauri/src/mcp.rs` manages the MCP server lifecycle:
+
+| Function | Purpose |
+|----------|---------|
+| `spawn_ws_bridge(vault_path)` | Spawns `ws-bridge.js` as child process with VAULT_PATH env |
+| `register_mcp(vault_path)` | Writes Laputa entry to Claude Code and Cursor MCP configs |
+| `upsert_mcp_config(path, entry)` | Atomic config file update (create/merge, preserves others) |
+
+The `WsBridgeChild` state wrapper in `lib.rs` ensures the bridge process is killed on app exit via `RunEvent::Exit` handler.

       → VaultEntry[] stored in state
    b. Load all content (mock mode) or on-demand (Tauri mode)
    c. invoke('get_modified_files') → ModifiedFile[] stored in state
-3. User clicks note in NoteList
+   d. useMcpRegistration → invoke('register_mcp_tools') → ensures MCP config current
+4. User clicks note in NoteList

+const AGENTS_MD: &str = r#"# AGENTS.md — Vault Instructions for AI Agents
+
+This is a [Laputa](https://github.com/refactoring-ai/laputa) vault — a folder of markdown files with YAML frontmatter that form a personal knowledge graph.
+
+## Structure
+
+Files are organized in folders by type:
+
+| Folder | Type | Purpose |
+|--------|------|---------|
+| `note/` | Note | General-purpose documents, research, meeting notes |
+| `project/` | Project | Time-bounded efforts with clear goals |
+| `person/` | Person | People — colleagues, collaborators, contacts |
+| `topic/` | Topic | Subject areas that group related notes |
+| `responsibility/` | Responsibility | Long-running duties with KPIs |
+| `procedure/` | Procedure | Recurring workflows (weekly, monthly) |
+| `event/` | Event | Something that happened on a specific date |
+| `quarter/` | Quarter | Time containers (e.g. 24Q1) |
+| `measure/` | Measure | Trackable metrics tied to responsibilities |
+| `target/` | Target | Time-bound goals for a measure |
+| `type/` | Type | Type definitions — icon, color, ordering |
+
+Custom folders are valid — the folder name becomes the type (capitalized).
+
+## Frontmatter
+
+YAML frontmatter between `---` delimiters defines metadata:
+
+```yaml
+---
+Is A: Project
+Status: Active
+Owner: "[[person/jane-doe]]"
+Belongs to: "[[quarter/24q1]]"
+Related to:
+  - "[[topic/growth]]"
+  - "[[note/research-findings]]"
+---
+```
+
+### Standard fields
+
+| Field | Purpose |
+|-------|---------|
+| `Is A` | Entity type (usually inferred from folder) |
+| `Status` | Active, Done, Paused, Archived, Dropped |
+| `Owner` | Person responsible (wikilink) |
+| `Belongs to` | Parent relationship(s) |
+| `Related to` | Lateral associations |
+| `Cadence` | For Procedures: Weekly, Monthly, etc. |
+| `aliases` | Alternative names for wikilink resolution |
+
+### Custom fields
+
+Any YAML field containing `[[wikilinks]]` becomes a navigable relationship:
+
+```yaml
+Has Measures: ["[[measure/revenue]]", "[[measure/churn]]"]
+Resources: "[[note/api-docs]]"
+```
+
+## Wikilinks
+
+Connect notes with double-bracket syntax:
+
+- `[[note/my-note]]` — link by path
+- `[[My Note Title]]` — link by title or alias
+- `[[note/my-note|display text]]` — link with custom display text
+
+Wikilinks work in both frontmatter values and markdown body. Backlinks are computed automatically — linking A to B makes B show a backlink to A.
+
+## Type definitions
+
+Files in `type/` define entity types and control how they appear in the sidebar:
+
+```yaml
+---
+Is A: Type
+icon: rocket-launch
+color: purple
+order: 1
+---
+```
+
+Available colors: red, purple, blue, green, yellow, orange. Icons are Phosphor names in kebab-case.
+
+## Conventions
+
+- First `# Heading` in a file becomes its title
+- One entity per file
+- Filenames use kebab-case: `my-note-title.md`
+- Type is inferred from parent folder if not set in frontmatter
+- Relationships are bidirectional via automatic backlinks

+
+# Welcome to Laputa
+
+Welcome to your new knowledge vault! Laputa helps you organize your thoughts, projects, and relationships using **wiki-linked markdown files**.
+
+## How it works
+
+Every note is a markdown file with optional YAML frontmatter at the top. Notes live in folders that define their **type** — a file in the `project/` folder is automatically a Project, a file in `person/` is a Person, and so on.
+
+## What to explore
+
+- [[note/editor-basics]] — Learn about headings, lists, checkboxes, and formatting
+- [[note/using-properties]] — See how frontmatter properties work (status, dates, relationships)
+- [[note/wiki-links-and-relationships]] — Connect your notes with `[[wiki-links]]`
+- [[project/sample-project]] — A sample project with relationships and status
+- [[person/sample-collaborator]] — A sample person entry
+
+## Tips
+
+- Press **⌘P** to quick-open any note by title
+- Press **⌘K** to open the command palette
+- Press **⌘N** to create a new note
+- Use the **sidebar** on the left to browse by type
+- Use the **inspector** on the right to edit properties and see backlinks

+---
+
+# Editor Basics
+
+Laputa uses a rich markdown editor. Here are the key formatting features:
+
+## Headings
+
+Use `#` for headings. The first H1 heading becomes the note's title.
+
+## Lists
+
+- Bullet lists use `-` or `*`
+- They can be nested
+  - Like this
+  - And this
+
+1. Numbered lists work too
+2. Just start with a number
+
+## Checkboxes
+
+- [x] Completed task
+- [ ] Pending task
+- [ ] Another thing to do
+
+## Text formatting
+
+You can use **bold**, *italic*, `inline code`, and ~~strikethrough~~ text.
+
+## Code blocks
+
+```javascript
+function hello() {
+  console.log("Hello from Laputa!");
+}
+```
+
+## Blockquotes
+
+> "The best way to have a good idea is to have lots of ideas." — Linus Pauling

+
+# Using Properties
+
+Every note can have **properties** defined in the YAML frontmatter at the top of the file. Properties appear in the inspector panel on the right side of the screen.
+
+## Common properties
+
+- **Is A** — The note's type (Project, Note, Person, etc.)
+- **Status** — Current state: Active, Done, Paused, Archived, Dropped
+- **Belongs to** — Parent relationship (e.g., a project belongs to a quarter)
+- **Related to** — Lateral connections to other notes
+- **Owner** — The person responsible
+
+## How to edit properties
+
+1. Open the **inspector panel** (right side)
+2. Click on any property value to edit it
+3. For relationship fields, type `[[` to search for notes
+4. Use the **+ Add property** button to add custom fields
+
+## Custom properties
+
+You can add any custom property. If the value contains `[[wiki-links]]`, Laputa will treat it as a relationship and show it as a clickable link in the inspector.

+  - "[[note/using-properties]]"
+---
+
+# Wiki-Links and Relationships
+
+Wiki-links are the core of Laputa's knowledge graph. They let you connect any note to any other note using the `[[double bracket]]` syntax.
+
+## Creating links
+
+Type `[[` in the editor to open the link suggestion menu. Start typing to search for a note, then select it. The link will look like this: [[note/welcome-to-laputa]].
+
+## Backlinks
+
+When note A links to note B, note B automatically shows a **backlink** to note A in the inspector panel. This means you never have to manually maintain bidirectional links.
+
+## Relationships in frontmatter
+
+You can also define relationships in the frontmatter:
+
+```yaml
+Belongs to: "[[project/sample-project]]"
+Related to:
+  - "[[note/editor-basics]]"
+  - "[[note/using-properties]]"
+```
+
+These appear as clickable pills in the inspector and are navigable with a single click.
+
+## Building your knowledge graph
+
+Over time, your wiki-links form a rich web of connections. Use the **Referenced By** section in the inspector to discover how notes relate to each other.
