Daniel 0f3a267fb6 Wire Alembic to live Postgres and fix startup DDL race 
- alembic.ini: remove hardcoded sqlite URL
- alembic/env.py: inject DATABASE_URL from container env
- main.py: serialize Base.metadata.create_all() + setup_pgvector() behind
  a Postgres advisory lock (_run_startup_ddl). Previously all 4 uvicorn
  workers ran the DDL in parallel and occasionally deadlocked each other
  on ALTER TABLE ordering, killing one worker at startup.
- CLAUDE.md: add Database migrations (Alembic) section
