feat: Multi-session support with tabs, split view, and Mochi integration

- Add SessionContext for central state management
- Add TabBar component for session tabs
- Add SplitLayout for side-by-side session viewing
- Add ChatPanel wrapper component
- Refactor ChatInput to uncontrolled input for performance
- Add SCP file transfer for SSH hosts (Mochi)
- Fix stats undefined crash on session restore
- Store host info in sessions for upload routing
