## What
Cache the Timmy agent instance at app startup (in lifespan) instead of creating a new one per `/serve/chat` request.
## Changes
- `src/timmy_serve/app.py`: Create agent in lifespan, store in `app.state.timmy`
- `tests/timmy/test_timmy_serve_app.py`: Updated tests for lifespan-based caching, added `test_agent_cached_at_startup`
2085 unit tests pass. 2102 pre-push tests pass. 78.5% coverage.
Closes#471

## Summary
- CognitiveTracker.update() now emits `cognitive_state_changed` events to the SensoryBus
- WorkshopHeartbeat (and other subscribers) react immediately to mood/engagement changes
- Closes the sense → memory → react loop described in the Workshop architecture
- Fire-and-forget emission — never blocks the chat response path
- Gracefully skips when no event loop is running (sync contexts/tests)
## Test plan
- [x] 3 new tests: event emission, mood change tracking, graceful skip without loop
- [x] All 1935 unit tests pass
- [x] Lint + format clean
Fixes#222

## What
Manually integrated unique code from two stale PRs that were **not** superseded by merged work.
### PR #399 (kimi/issue-362) — WebSocket heartbeat ping
- 15-second ping loop detects dead iPad/Safari connections
- `_heartbeat()` coroutine launched as background task per WS client
- `ping_task` properly cancelled on disconnect
### PR #408 (kimi/issue-322) — Conversation commitment tracking
- Regex extraction of commitments from Timmy replies (`I'll` / `I will` / `Let me`)
- `_record_commitments()` stores with dedup + cap at 10
- `_tick_commitments()` increments message counter per commitment
- `_build_commitment_context()` surfaces overdue commitments as grounding context
- Wired into `_bark_and_broadcast()` and `_generate_bark()`
- Public API: `get_commitments()`, `close_commitment()`, `reset_commitments()`
### Tests
22 new tests covering both features: extraction, recording, dedup, caps, tick/context, integration, heartbeat ping, dead connection handling.

This PR rescues unique code from stale PRs #399 and #408. The other two stale PRs (#402, #411) were already superseded by merged work and should be closed.
