Was: malformed event (bad JSON / truncated / corrupted bytes) wedged the
node's checkpoint forever — every cycle re-tried, logged, never advanced
past the bad file; all subsequent good events for that node lost.
Now: first parse failure -> atomic os.replace to STATE_DIR/observer_failed_events/<node>/
with collision handling. Checkpoint advances, downstream events flow.
Move failures themselves are logged but don't crash the loop.
Complementary to yesterday's atomic_write_json fix (state files);
this addresses the same race-pattern on event files instead.
Regression test asserts: bad event quarantined to failed_events dir,
removed from hot path, subsequent good event processed (node online),
checkpoint moves to good event.
- main.py: rename event= to ha_event= in _log.warning() — structlog treats
'event' as a reserved positional arg; the old name caused TypeError when
any check returned unhealthy results (events were still emitted, but the
check was logged as check_error instead of check_unhealthy)
- tests/test_ha_client.py: replace aioresponses with unittest.mock — aioresponses
0.7.8 is incompatible with aiohttp >=3.12 (missing stream_writer kwarg)
- pyproject.toml: remove aioresponses from dev dependencies

- dockerized ken + chelsty HA test instances with template fixtures
- snapshot/reset/wait scripts for fixture management
- integration test infrastructure with separate marker
- location_tag promoted from metadata to event payload (Phase 1 flag #3)
- chelsty-infra target_url points to chelsty-ha via tailnet (Phase 1 flag #1)

- new per-host service, follows node-agent pattern
- 7 new HA event types defined (routing in supervisor — Phase 5)
- HeartbeatCheck as pipeline validator (pings /api/, emits ha_websocket_dead)
- service.yaml + host configs for piha (ken) and chelsty-infra (chelsty)
- test scaffolding with aiohttp/aiosqlite mocks (15/15 passing)
