feat(studio): add tool execution and hide AI thinking tags

Changes:
- Hide <think> tags from user in Studio chat
- Add tool call detection [TOOL_CALL:{...}] in AI responses
- Execute crush tool when requested by AI
- Show loading animation while AI is thinking

The AI can now:
1. Respond directly to user
2. Request tool execution via [TOOL_CALL:{"tool":"crush","task":"..."}]

The system automatically executes the tool and includes results.

CHANGELOG.md

@@ -6,8 +6,35 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 
 ## [Unreleased]
 
+### Security
+
+- **Command injection**: Removed non-functional AI sidebar from Shell.jsx that interpolated user input directly into a shell command (`echo "AI: ${text}"`). The panel was a stub with no real AI integration.
+- **WebSocket origin validation**: Terminal WebSocket handler now validates the `Origin` header matches the server's own host.
+- **DELETE method guard**: Terminal sessions DELETE endpoint now rejects non-DELETE methods.
+
+### Fixed
+
+- **Message ID collisions**: `generateMsgID()` now appends nanosecond suffix to prevent collisions under rapid creation.
+- **Legacy dir migration**: Config migration from `~/.muyue` to XDG path now logs errors instead of silently failing.
+- **MCP JSON parsing**: `json.Unmarshal` errors in MCP config loading are now handled instead of ignored.
+- **API header merging**: `client.js` `request()` now correctly merges caller headers with defaults (was overwriting `Content-Type`).
+- **Variable shadowing**: `t` translation function shadowed by `.filter(t => ...)` in Config.jsx and App.jsx — renamed to `tool`.
+
+### Changed
+
+- **Real SSE streaming**: Chat endpoint now streams AI responses via SSE (`data: {"content":"..."}` chunks) instead of fake 8-rune chunking. Frontend renders responses progressively as they arrive.
+- **Progressive rendering**: Studio.jsx now uses `StreamingItem` component to display partial AI output during streaming, with cursor animation.
+- **Theme from config**: App.jsx loads theme from user profile preferences on startup (was hardcoded to `cyberpunk-red`).
+- **Handlers split**: Monolithic `handlers.go` split into 6 focused files: `handlers_common.go`, `handlers_info.go`, `handlers_tools.go`, `handlers_config.go`, `handlers_chat.go`, `handlers_terminal.go`.
+- **Dynamic version**: Config `Version` field now uses `version.Version` constant instead of hardcoded `"0.1.0"`.
+- **Path construction**: `filepath.Join` used consistently in installer, MCP, scanner, and profiler for cross-platform safety.
+- **CI Go version**: All 3 CI workflows updated from `go-version: '1.24.3'` to `'1.24'` to match `go.mod`.
+- **Dead code removed**: Unused `addNotif` function in Dashboard.jsx, unused `layout` destructuring, dead `tools`/`updates`/`onRescan` props, dead AI sidebar in Shell.jsx, associated CSS and i18n keys.
+
 ### Added
 
+- **SendStream tests**: 3 new tests for the SSE streaming method (chunk parsing, history accumulation, API error handling) using `httptest` server.
+
 - **Desktop mode**: React 19 web UI served locally, auto-opens in browser. Frontend embedded in Go binary via `go:embed`.
 - **API backend**: 15 REST endpoints (`/api/info`, `/api/system`, `/api/tools`, `/api/config`, `/api/providers`, `/api/skills`, `/api/lsp`, `/api/mcp`, `/api/updates`, `/api/scan`, `/api/install`, `/api/terminal`, `/api/mcp/configure`, `/api/preferences`).
 - **i18n**: Full FR/EN translation system with keyboard layout awareness (AZERTY, QWERTY, QWERTZ). Preferences synced to backend.
