feat: group chat session lifecycle, typing recovery, mention highlighting (#186)
* feat: restore group chat system with Socket.IO and SQLite persistence - GroupChatServer: Socket.IO server with room management, message history, typing indicators - SQLite storage for rooms, messages, and agent configuration - AgentClients: manages AI agent connections via socket.io-client, forwards @mentions to Hermes gateway - REST API: room CRUD, agent management, invite codes - Agent auto-restoration on server restart - Tests for all REST endpoints Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * docs: add context-engine design document for group chat compression Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: handle special-character session search * fix: keep unicode dotted session search on quoted FTS path * feat: add context engine and group chat frontend UI - Context engine: three-zone compression (head/tail/summary) with LLM summarization, incremental updates, TTL cache, and graceful degradation - Frontend: group chat page with Socket.IO client, room sidebar, message list, agent/member display, create/join-by-code modals - Integration: wire context engine into agent-clients before /v1/runs - Refactor ChatStorage to use global DB (getDb/ensureTable) with gc_ prefix - Add i18n keys for group chat to all 8 locales - Add sidebar nav entry and router for group chat page Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: remove leftover main branch code from merge conflict resolution The `isNumericQuery`, `hasUnsafeChars`, and `runLikeContentSearch` functions no longer exist — they were replaced by HEAD's `shouldUseLiteralContentSearch` and `runLiteralContentSearch`. This dead code block caused a TypeScript compile error after the merge. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: install missing socket.io dep and type ack params Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: enable WebSocket proxy and fix socket.io transport for group chat - Add ws: true to Vite proxy config so WebSocket upgrade requests are forwarded to the backend - Allow both polling and websocket transports on server and client (polling as fallback when WebSocket upgrade fails through proxy) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: separate socket.io path from REST routes for group chat socket.io was mounted at /api/hermes/group-chat which intercepted all REST requests to /api/hermes/group-chat/rooms etc, returning "Transport unknown". Changed socket.io path to /api/hermes/group-chat/ws to avoid conflicts. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: improve group chat UI, agent management, and socket.io reliability - Redesign GroupChatPanel with Naive UI, stacked agent avatars, and popover management - Match GroupChatInput style with single chat input, add IME composition handling - Add agent add/remove per room with profile selection and duplicate prevention - Use @multiavatar for SVG avatar generation with caching - Decouple joinRoom from socket.io, use REST API for data loading - Switch socket.io to default path with /group-chat namespace to avoid proxy conflicts - Restore agent connections after server is listening - Add getRoomDetail REST endpoint and duplicate agent prevention (409) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: server-side @mention routing with context compression status and queue - Move @mention detection from agent socket listeners to server-side processMentions() - Add per-room processing lock to block mention dispatch during compression - Queue mentions during processing, drain only the latest when ready - Emit context_status events (compressing/replying/ready) to room via Socket.IO - Frontend displays compression status indicator above input - Token-based compression trigger (100k threshold) with CJK-aware estimation - Fix compressor type errors (countTokens parameter type) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: improve group chat profile handling and session sync Refine group chat room/session behavior with per-room compression controls, sidebar updates, and better stale session cleanup so multi-profile group chat state stays consistent. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: group chat improvements — session lifecycle, typing recovery, mention highlighting - Fix cross-profile session deletion with deferred delete queue - Move saveSessionProfile to after gateway response confirmation - Replace all console.log with logger in group-chat modules - Add server-side typing/context_status state tracking for room rejoin - Fix @ mention popup position to follow cursor - Add @ mention highlighting (blue) in chat message content - Fix mention regex to match all occurrences after HTML tags - Enable esbuild minify and treeShaking - Move @multiavatar/multiavatar to devDependencies - Add i18n keys for group chat features - Update tests for new functionality Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: bump version to 0.4.5 and move @multiavatar to devDependencies Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: Zhicheng Han <zhicheng.han@mathematik.uni-goettingen.de>
