uv-replaces-pip-as-python-package-manager

New Python projects in the Runwal stack use uv as the package manager (10-100× faster than pip, supports uv workspaces for monorepos). This is the 2025 standard adopted for R-Same’s backend. Equivalent role to pnpm for the JS side. Any new Python service scaffolding should use pyproject.toml + uv, not pip/requirements.txt.
