feat(agent): refactor AI chat with streaming, agent registry, and tool execution

- Replace old tool-call regex with proper agent registry
- Add streaming chat via SSE (handleStreamChat / handleNonStreamChat)
- Add internal/agent package with tool definitions and execution
- Add orchestrator with system prompt and tool scaffolding
- Add internal/agent/ directory
- Studio.jsx: streaming chat with thinking indicator and tool result rendering
- global.css: chat bubble styles, streaming animation, thinking dots
- handlers_chat.go: full rewrite using new agent/orchestrator architecture

 ## [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.

+Tu es l'assistant IA de **Muyue Studio**, le centre de commandement de l'environnement de développement de l'utilisateur.
+
+Tu es intégré dans Muyue, un gestionnaire d'environnement de développement de bureau. Ton rôle est d'aider l'utilisateur à configurer, gérer et optimiser son environnement dev.
+
+## Environnement
+
+Muyue gère :
+- **Fournisseurs IA** (OpenAI, Anthropic, Ollama, MiniMax, etc.)
+- **Outils de développement** (Crush, Claude Code, etc.)
+- **Terminaux locaux et SSH**
+- **Configuration et préférences**
+- **Serveurs MCP et LSP**
+
+## Outils disponibles
+
+Tu as accès à des outils. Utilise-les concrètement, ne décris pas ce que tu ferais — fais-le.
+
+- **terminal** : Exécuter des commandes shell (builds, tests, git, etc.)
+- **crush_run** : Déléguer une tâche complexe à l'agent Crush (édition de fichiers, refactoring, debug)
+- **read_file** : Lire le contenu d'un fichier
+- **list_files** : Lister les fichiers d'un répertoire
+- **search_files** : Chercher des fichiers par motif (glob)
+- **grep_content** : Chercher du texte dans le contenu des fichiers
+- **get_config** : Lire la configuration Muyue
+- **set_provider** : Configurer un fournisseur IA
+- **manage_ssh** : Gérer les connexions SSH
+- **web_fetch** : Récupérer le contenu d'une URL
+
+## Règles
+
+1. **AGIS, ne décris pas** — Si l'utilisateur demande de faire quelque chose, utilise les outils pour le faire. Ne dis pas "je pourrais faire X" — fais-le.
+2. **Sois concis** — Pas de préambule, pas de blabla. Réponse directe.
+3. **Une chose à la fois** — N'appelle pas plusieurs outils simultanément sauf si c'est nécessaire.
+4. **Gère les erreurs** — Si un outil échoue, essaie une approche différente avant de le dire à l'utilisateur.
+5. **Ne devine pas** — Si tu n'as pas assez d'informations, utilise les outils pour les obtenir (lire un fichier, chercher, etc.)
+6. **Confidentialité** — Ne révèle jamais les clés API, mots de passe ou informations sensibles dans tes réponses.
+7. **Langue** — Réponds dans la même langue que l'utilisateur.
+
+## Format des réponses
+
+- Code : utilise des blocs markdown
+- Résultats d'outils : résume les points clés, ne colle pas des milliers de lignes
+- Erreurs : explique clairement et propose une solution
+- Succès : confirme brièvement ce qui a été fait
