- Change BaseChat2 key from sessionId to stable tab.id
- Prevents component remounting when session ID changes from temporary to real
- Maintains chat state and messages when new sessions are created
- Messages now persist correctly when sending first message in new tab
The issue was that using sessionId as the React key caused the component
to unmount and remount when the backend assigned a real session ID,
clearing all state. Using the stable tab ID prevents this.
- Add onSessionIdChange callback to useChatStream hook
- Notify tab context when new session gets real backend ID
- Update tab's session ID when backend creates new session
- Prevents message clearing when sending first message in new tab
This fixes the issue where new tabs would show messages briefly
then clear them because the temporary session ID didn't match
the real session ID created by the backend.

- This eliminates 404 errors when creating new chat tabs
🐛 Problem Fixed:
- Tabbed interface always created new sessions instead of loading existing ones
- 'Resume from history' opened blank chats instead of loading conversation history
- useChatStream hook only supported new session creation, not existing session loading
- No integration with existing session management and resumeAgent API
✨ Solution Implemented:
- Enhanced useChatStream to attempt loading existing sessions via resumeAgent API
- Added smart session detection - only creates new for IDs starting with 'new_'
- Implemented openExistingSession method in TabContext for existing session support
- Added URL parameter handling for resumeSessionId in TabbedPairRoute
- Session deduplication prevents opening same session in multiple tabs
🔧 Technical Implementation:
- Modified useChatStream session loading logic to try resumeAgent first
- Added fallback to new session creation if resume fails
- Integrated with existing backend session management APIs
- Added automatic title synchronization for opened existing sessions
- URL parameter cleanup to prevent re-opening on refresh
🎯 User Experience:
- Resume from history now properly loads conversation history
- Existing sessions open with full message history and proper titles
- Clicking same session switches to existing tab instead of creating duplicate
- Seamless integration with existing session management workflow
📋 Features Added:
- Smart session detection (new_ prefix vs existing session IDs)
- Existing session loading with conversation history
- URL parameter support for session resumption (resumeSessionId)
- Tab deduplication for same session IDs
- Automatic title loading from backend for existing sessions
- Error resilience with fallback to new session creation

- Integrated with existing getSession and updateSessionDescription APIs
- Graceful error handling - continues working if backend sync fails
🎯 User Experience:
- Tabs now show meaningful conversation titles instead of 'New Chat'
- First message (up to 47 chars) becomes the tab title automatically
- Existing session titles are loaded when tabs are restored
- Titles persist across app restarts via backend storage
📋 Smart Title Logic:
- Detects first user message and generates title
- Truncates long messages with ellipsis (47 chars + '...')
- Fallback to timestamp-based titles for empty messages
- Immediate local updates + async backend persistence
🔄 Backend Integration:
- Uses existing Session.description field for persistence
