Composer restructure:
- MessageInput internal footer now only contains: file button, model
selector, slash command button, and send button
- Removed mode toggle (Code/Plan) from composer area (logic preserved)
- New ChatComposerActionBar below input with three slots: left (Design
Agent), center (permission selector), right (context indicator)
New components:
- SlashCommandButton: inserts `/` at cursor, reuses existing slash
command detection and popover logic
- ChatPermissionSelector: session-level permission toggle (default /
full_access) with danger confirmation dialog
- ContextUsageIndicator: SVG donut chart showing context usage ratio
with HoverCard displaying model, tokens, cache stats
- ChatComposerActionBar: slot-based container for action bar items
Session permission (permission_profile):
- DB: new column on chat_sessions, default 'default'
- API: PATCH sessions supports updating permission_profile
- Chat API: bypassPermissions = global setting OR session full_access
- PermissionPrompt: auto-approves and hides when full_access
- Claude client: combines global and per-session bypass flags
Bridge integration:
- permission-broker: auto-approves permissions for full_access sessions
without sending IM notifications
- conversation-engine: passes bypassPermissions to SDK for full_access
- PATCH route: auto-approves pending bridge permissions on switch to
full_access
Other:
- ImageGenToggle relabeled to "Design Agent" / "设计 Agent"
- New model-context.ts with MODEL_CONTEXT_WINDOWS lookup
- Provider models API returns optional contextWindow field
- New useContextUsage hook for token usage calculation
- i18n: added composer.*, permission.*, context.* keys (en + zh)

Image Generation Refactor:
- MessageInput: add onImageGenerate callback, remove skill fetch dependency
- ChatView: implement handleImageGenerate that creates image-gen-request
message for ImageGenConfirmation UI, then user selects params and generates
- New API route POST /api/chat/messages for DB-only message persistence
- image-gen-completed event now only persists notice to DB, no longer triggers model
- Reference images passed via module-level Map (imageGenRefStore) to avoid
DB bloat from base64 data; user message DB content stores metadata only
Bug Fixes:
- Fix useCallback dependency missing imageGen causing stale closure reads
- Fix React Hooks order violation in MessageItem (early return before hooks)
- Fix localStorage cache collision across sessions (key now includes sessionId)
- Fix empty src attribute in FileAttachmentDisplay for DB-restored messages
- Add JSON parse fallback for malformed image-gen-request blocks
Gallery Reference Images:
- /api/media/generate saves reference images to disk, stores paths in metadata
- /api/media/gallery extracts referenceImages from metadata in mapRow
- GalleryDetail displays reference image thumbnails
- ImageGenCard supports referenceImages prop for chat display
UI Changes:
- ImageGenToggle: replace paint brush icon with text label (en: Image, zh: 生图)
- Model selector button: remove provider name display to save space
- ImageGenConfirmation: support referenceImagesData prop for base64 preview
i18n:
- Add imageGen.toggleLabel key (en: Image, zh: 生图)
