Complete Zustand migration: fix component access to session APIs

Finalizes the pure Zustand refactor by ensuring all components properly access both session state and imperative methods through useDaemonSession. Moves CLAUDE.md to root and ignores local overrides.

Changes:
- Fix useDaemonSession to return stable combined state + methods object
- Update components to use useDaemonSession instead of direct context
- Fix realtime context to work with session state only
- Move CLAUDE.md to root, ignore CLAUDE.local.md for local config
- Add proper null checks and type safety throughout
