Rolls back the claudification backend preference: PREFER_CLOUD_BACKEND now
defaults to false, resolve_backend() picks Ollama first and uses Claude when
explicitly preferred or when the new Ollama startup health check fails. The
Steward retries mid-request failures on the other backend in both directions.
Also hardens the fallback itself: Anthropic SDK imports are lazy so a broken
anthropic package degrades to Ollama-only instead of crashing at import time
(root cause of the production outage since April), anthropic is pinned to a
pydantic-ai-1.27-compatible range, ANTHROPIC_MODEL defaults to claude-sonnet-5
(sonnet-4-20250514 retired 2026-06-15), sampling parameters are stripped from
Claude calls (Sonnet 5 rejects them), and the Steward timeout is configurable
(STEWARD_TIMEOUT, default 60s) since gemma4 needs ~35s warm for analysis.

- Remove references to unimplemented get_benchmark_store from steward and
tool tracking tests
- Fix steward test fixture calling async initialize_application synchronously
by using sync register_household_members instead
- Rewrite tool tracking tests to assert actual logging behavior
- Change unit test fixture model from Tatlock to lorem-tester so unit tests
don't require external services
- Add session-scoped _initialize_app fixture to run Claude health check,
ensuring integration tests use Claude instead of falling back to Ollama
- Increase integration test timeouts from 30s to 120s to match OLLAMA_TIMEOUT
- Add Steward reasoning as ReasoningOutputItem in create_response_with_steward
so <think> tags appear in chat completion responses
- Add test_tatlock_ollama_fallback to verify Ollama fallback path works

Implements The Housekeeper, a new expert agent for home automation
following the Librarian pattern. Communicates with core-api service
which wraps Home Assistant REST API.
New agent features:
- CoreAPIClient with 13 home automation methods
- 13 tools: list_areas, list_devices, get_device_state, turn_on,
turn_off, toggle, list_scenes, activate_scene, list_scripts,
run_script, list_automations, toggle_automation, get_history
- PydanticAI agent with butler-friendly system prompt
- HouseholdCapability registration for Steward coordination
- delegate_to_housekeeper() wrapper for orchestration
Also includes:
- Dev port changed from 8123 to 8777 (avoids Home Assistant conflict)
- Config: CORE_API_HOST, CORE_API_KEY, CORE_API_TIMEOUT
- 44 unit tests for client and capability
