The source code was moved to v1/src/ but the Dockerfile still referenced src/ directly, causing build failures. Updated all COPY paths, uvicorn module paths, test paths, and bandit scan paths. Also added missing v1/__init__.py for Python module resolution. Fixes #33 Co-Authored-By: claude-flow <ruv@ruv.net>
