- Create reactive featureFlagsStore for centralized feature flag management
- Fix race conditions in feature flag updates with version tracking
- Make managerStateStore properly reactive to feature flag changes
- Add useManagerHelper composable as single entry point for opening manager
- Fix Legacy UI keybinding fallback to new manager when appropriate
- Update WebSocket handler to sync feature flags with reactive store
- Add comprehensive tests for all manager UI states
This ensures the Manager UI state (NEW_UI, LEGACY_UI, DISABLED) updates
reactively when feature flags change, fixing the issue where manager
state wasn't properly responding to server capability changes.
