feat: initial FastAPI boilerplate setup

Set up Webber - multi-agent AI development system with:

- Domain-based project structure (src/domains/, src/shared/)
- BaseController pattern with lazy router instantiation
- Pydantic Settings configuration with env file support
- Logger decorator with temporal benchmarking and trace IDs
- UserProvider singleton for request-scoped context
- Custom exception hierarchy
- Health endpoints (/, /health)

Dependencies (CVE checked 2026-01-09):
- FastAPI 0.128.0, Starlette 0.50.0, Uvicorn 0.40.0
- Pydantic 2.12.4, PydanticAI 1.40.0
- All packages at latest safe versions

Placeholder domains for future implementation:
- agents/ (explore, plan, task)
- tools/ (file, shell, search)
- auth/ (tatlock integration)

Port: 8086 (per CONTAINERS.md allocation)
