Summary

M3-007: Add periodic health check scheduler to — runs on all registered adapters at a configurable interval ( env, default 60s), caches results per provider, and exposes returning .
M3-009: Refactor to be provider-agnostic: defaults to Ollama native with model (768 dims); falls back to OpenAI-compatible API when or is set; respects , , env vars; logs a dimension mismatch warning when switching from 1536-dim OpenAI vectors.

Test plan

typecheck: pass
lint: pass
format:check: pass
Verify GET /api/providers/health returns provider list with status fields
Verify EmbeddingService uses Ollama when OLLAMA_BASE_URL is set
Verify EmbeddingService falls back to OpenAI when OPENAI_API_KEY is set and no Ollama URL
Verify dimension mismatch warning logged when dimensions differ from pgvector schema

M3-007: Add periodic health check scheduler to ProviderService (configurable
via PROVIDER_HEALTH_INTERVAL env, default 60s) with cached status per adapter,
and expose GET /api/providers/health endpoint returning { providers: [...] }.

M3-009: Refactor EmbeddingService to default to Ollama (nomic-embed-text, 768
dims) with OpenAI-compatible fallback when EMBEDDING_PROVIDER=openai or
OPENAI_API_KEY is set; add dimension mismatch warning for pgvector schema.
