feat: add event bus, WS workspace isolation, and global store migration

Browse source 
- Add internal event bus (server/internal/events/) with synchronous
  pub/sub and panic isolation per listener
- Upgrade WebSocket Hub to workspace-scoped rooms with JWT auth
  and membership verification on connect
- Add 10 new WS event types (comment CRUD, inbox read/archive,
  agent create/delete, workspace/member events)
- Refactor all handlers and TaskService to publish events via Bus
  instead of direct Hub.Broadcast calls
- Add WS broadcast listener that routes events to correct workspace
- Frontend: WSClient sends token + workspace_id on connect with
  auto-reconnect refetch
- Frontend: centralized useRealtimeSync hook dispatches all WS
  events to global Zustand stores
- Migrate issues and inbox pages from local useState to global
  useIssueStore/useInboxStore
- Make store addIssue/addItem idempotent to prevent duplicates
- Remove dead packages/hooks/src/use-realtime.ts
- Add feature tracking files for 4 planned features
