Refactor real-time sync from per-event precise mutations to WS-as-invalidation-signal + debounced refetch.
Backend:
- Add SubscribeAll to Event Bus — auto-broadcasts ALL events, eliminates manual 25-item allEvents list
- Add skill event constants to protocol, fix skill handler string literals
- Add title_changed activity tracking
Frontend:
- WSClient: add onAny() method for wildcard event subscription
- useRealtimeSync: rewrite to refreshMap + prefix routing + 100ms debounce
- Precise handlers only for side effects: workspace:deleted, member:removed, member:added (self-check)
- Reconnect now refetches all stores (fixes missing members/skills/workspace refresh)
- Stale-while-revalidate: fetch() only shows loading spinner on initial load, not on refetch
- Remove redundant useWSEvent in agents/page.tsx and skills-page.tsx
- WSClient.disconnect() now clears all handler registrations
Inbox bugfixes:
- Unify sidebar badge count with page count via dedupedItems + unreadCount in store
- Sort by time DESC (removed severity-first ordering)
- Ellipsis on truncated detail labels
UI:
- Status/Priority pickers: replace RadioGroup with MenuItem for auto-close on selection
