feat: replace Agent mode with independent Tools toggle

- Remove 'agent' from mode dropdown; Chat/Note/OTR remain
- Add ⚡ tools toggle button in input bar (persisted in localStorage)
  When on: routes to POST /orchestrate (Gemini tool loop); send btn → "Run"
  When off: routes to POST /chat (direct to active role); no change
- Role selector and tools toggle are now fully independent:
  active chat_role sent in orchestrate payload → used for final response
- orchestrator_engine.run() accepts response_role param; passes it to
  complete(role=...) instead of hardcoded model="claude"
- OrchestrateRequest gains chat_role field (default "chat")
- Migrate stored 'agent' mode/MRU entries to 'chat' on load
