Three fixes:
1. Status bar now shows model/provider from ProviderStatusChanged:
- RootReducer sets currentModel and providerType when the message arrives
- providerType is LOCAL for llama/local providers, REMOTE otherwise
- Removes the stale '(no model) (local)' display
2. SessionSnapshot now carries recent event history:
- New EventEntryDto in the protocol with timestamp/type/detail
- SessionSnapshot.recentEvents populated by bridge from event store
- Bridge reads last 7 display-relevant events per session
- TUI processSessionSnapshotMessage maps them to TuiEventEntry
- Completed sessions finally show their event history
3. SessionStarted now switches selectedId to the new session:
- RootReducer cross-field weave updates selectedId alongside sessionEntered
- Previously kept the old selectedId, navigating user into the wrong session
- Works whether starting a session from the list or during replay
