feat/general-refinement - Fix Dockerfile merge conflict by keeping stdio-only MCP configuration

- Remove HTTP/port-related configurations (PORT, TRANSPORT, EXPOSE)
- Keep Python 3.13-slim base images for latest Python version
- Maintain process-based health check using pgrep instead of HTTP curl
- Ensure MCP server remains stdio-only as intended for MCP protocol
- Resolve merge conflict with main branch while preserving Python 3.13 upgrade
