Add search backend: FastAPI + FastMCP + pgvector for docs Q&A and live SQL
Search stack replicates the Hamilton site pattern with pg_orrery-specific
additions:
- FastAPI REST API (chat SSE streaming, semantic search, health check)
- FastMCP server at /mcp with doc search and live SQL query tools
- pgvector + pgai vectorizer for 1024-dim document embeddings
- Hybrid search (semantic cosine + text ILIKE with pg_trgm GIN)
- Dual LLM backend: self-hosted qwen3 via GPU gateway or Anthropic Claude
- Live read-only pg_orrery SQL execution with safety guardrails
(SELECT-only validation, read-only transaction, 5s timeout, 100-row cap)
- Convenience MCP tools: planet_position, sky_survey, satellite_pass
- MDX content ingestion from docs/src/content/docs/ (50 pages)
- Docker Compose: pg_orrery+pgvector DB, pgai, vectorizer-worker, API
- Alembic async migrations, Makefile, .env.example
