feat: add multi-daemon support with session routing and connection management

Introduce DaemonRegistry and DaemonConnections contexts for managing multiple server connections. Add session directory for aggregating agents across daemons, with automatic routing based on agent/server context.

Key changes:
- Add daemon profile management (add/edit/remove/set default)
- Implement connection state tracking with reconnection and exponential backoff
- Create useAggregatedAgents hook for unified agent list across daemons
- Add useDaemonSession and useDaemonRequest hooks for daemon-scoped operations
- Update agent routes to include serverId for proper session routing
- Add connection health indicators on home screen and settings
- Persist session snapshots per daemon for faster hydration on reconnect
- Guard screens gracefully when target daemon is offline
- Add React Query for consistent loading/error state management
