Fixed DATABASE_URL to use standard postgresql:// scheme, hardcoded DB
credentials for dev simplicity, added API_KEY pass-through, set worker
working_dir, and made JWT_SECRET optional with dev default. All 5 services:
db (:5434), redis, api (MCP :8401), worker (Celery), web (:8400).
Add README.md with project description, quick-start instructions, and
AGPL-3.0 license badge. Add .gitignore for Python, Node, and Docker
artifacts. Include existing CLAUDE.md, spec, docker-compose.yml, and
env.example.
