This PR addresses the user's request to fix Chat UI issues (message ordering, left panel updates) and implements a debugging framework.

Key Changes:

  1. Chat UI Fixes:

    • Ordering: The user message now correctly stays above the assistant response during streaming. Previously, the optimistic update logic would push the user message to the bottom when the real response arrived. I refactored setMessages to update the placeholder in-place.
    • Dynamic Updates: The left-hand chat list (Dashboard) now updates immediately when a message is sent or received, by invalidating the dashboard query.
  2. Debugging Framework:

    • Backend: The process_turn engine now returns metadata about the agent used (INTAKE, FEEDBACK, COACH) and the tools available to it. This is exposed in the API response.
    • Frontend: An admin-only toggle in the Settings/Admin page enables "Chat Debug Mode". When active, assistant messages display a small footer showing the active agent, tools, and reasoning.
  3. Agent Capabilities:

    • Fixed the issue where the agent couldn't schedule nudges. The COACH agent now has access to scheduler_tools (schedule_nudge, etc.) when running in LLM mode.

Verification:

  • Ran backend unit/integration tests (uv run pytest).
  • Ran frontend E2E tests (npm run test:e2e) to verify chat flows.
  • Manual verification logic implemented in MessageBubble and ChatThread.

- **Backend**:
  - Injected scheduler tools (`list_schedules`, `schedule_nudge`, `delete_schedule`) into the `COACH` agent in `api/app/agents/engine.py`.
  - Updated `process_turn` to return `tools_used`.
  - Updated `SendMessageResponse` in `api/app/routes.py` to optionally include `debug_info` (agent, tools, reason).

- **Frontend**:
  - Fixed message ordering in `ChatThread.tsx` by using `map` instead of filtering/pushing, ensuring the user message stays above the streaming assistant response.
  - Added `queryClient.invalidateQueries` to update the Dashboard chat list preview immediately upon sending/receiving messages.
  - Implemented "Chat Debug Mode" toggle in Admin panel (`web/src/pages/Admin.tsx`).
  - Updated `MessageBubble` to render debug info (Agent, Tools, Reason) when enabled by admin.
  - Regenerated OpenAPI types.

- **Verification**:
  - Added integration tests for backend engine logic.
  - Validated frontend via E2E tests (`chat.spec.ts`).
