fix: persist last vault path so app reopens correct vault after update

The vault path was stored only in React state (useState), which resets
on every app restart. Now the last active vault path is written to
~/Library/Application Support/com.laputa.app/last-vault.txt on every
vault switch, and loaded on startup. If the saved vault no longer exists,
the existing onboarding flow shows the vault picker instead of silently
falling back to the demo vault.

+# 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.

+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.
