This is a known pip dependency resolution behavior — when ruff>=0.8.0 has a wide version range, pip's resolver may download multiple versions to find a compatible combination.

Quick workaround: Use uv instead of pip for much faster installs:

pip install uv
cd ~/Clawith/backend && uv pip install -e '.[dev]'

We've also pinned ruff to a specific version range to reduce the backtracking. This should not affect Docker users since dev dependencies are not installed in containers.
