fix: runtime deployment fixes for Docker Compose stack

- Add .gitignore for __pycache__, node_modules, .playwright-mcp
- Add CLAUDE.md project instructions
- docker-compose: remove host port exposure for internal services,
  remove Ollama container (use host), add CORS origin, bake
  NEXT_PUBLIC_API_URL at build time, run alembic migrations on
  gateway startup, add CPU-only torch pre-install
- gateway: add CORS middleware, graceful Slack degradation without
  bot token, fix None guard on slack_handler
- gateway pyproject: add aiohttp dependency for slack-bolt async
- llm-pool pyproject: install litellm from GitHub (removed from PyPI),
  enable hatch direct references
- portal: enable standalone output in next.config.ts
- Remove orphaned migration 003_phase2_audit_kb.py (renamed to 004)
