feat: render markdown in AI Chat assistant responses

Replace regex-based bold/newline rendering with react-markdown + remark-gfm
+ rehype-highlight for full markdown support: bold, code blocks with syntax
highlighting, bullet/ordered lists, headers, blockquotes, links, tables.

-Task: pencil-ui-design-light-mode
-Summary: Verified all 115 top-level frames in ui-design.pen have theme:{Mode:Light}. No remaining before-variant frames found (only legitimate state-transition labels). No duplicate frames detected. Visual screenshots confirm correct light-mode rendering. Previous commit 165cc0e already applied theme to 25 dark-mode frames and removed 2 before variants.

+# 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.
