Oskar Kapala dcacac6965 fix(planner-agent): rename OLLAMA_HOST → OLLAMA_API_BASE (litellm convention)
LiteLLM reads OLLAMA_API_BASE, not OLLAMA_HOST.
- llm_router.py: DEFAULT_OLLAMA_HOST → DEFAULT_OLLAMA_API_BASE, param ollama_host → ollama_api_base
- planner.py: env var os.getenv("OLLAMA_HOST") → os.getenv("OLLAMA_API_BASE"), param renamed accordingly
- /opt/homelab/config/planner-agent/.env on SOLARIA updated in-place (not in git)

Oskar Kapala 1bbc511bb7 feat(planner-agent): add llm_router.py with local-first fallback chain
services/planner-agent/src/llm_router.py:
- LLMRouter: async routing via litellm; chain = Qwen/Ollama → haiku → sonnet
- Timeouts: 8s local, 30s cloud; asyncio.wait_for belt-and-suspenders
- Rejection triggers: timeout, API error, refusal patterns, JSON schema fail
- JSON fence extraction: recovers valid JSON from  blocks
- ModelMetrics: per-model success/fallback/error counters + success_rate()
- Redis publish to 'llm_router_metrics' after every call (failure-safe)
- redis_url=None disables Redis (useful in tests / edge nodes)
- context= param adds caller label to all log lines for tracing

services/planner-agent/tests/test_llm_router.py:
- 34 tests, 0 network calls (litellm + Redis fully mocked)
- Covers: primary success, JSON error fallback, refusal fallback,
  timeout fallback, API exception fallback, all-fail RuntimeError,
  schema validation, fence extraction, metrics recording, Redis publish,
  Redis failure isolation

services/planner-agent/requirements.txt:
- litellm>=1.40.0, redis>=5.0.0, jsonschema>=4.21.0
