Use uv-venv-lock-runner to respect uv.lock in tox

oschwald · claude · oschwald · commit 68bb667b1903 · 2026-02-24T09:09:30.000-08:00
The default uv-venv-runner uses uv pip install which ignores the lock file. Switch to uv-venv-lock-runner so tox environments use uv sync --locked and install the exact versions pinned in uv.lock. See tox-dev/tox-uv#288 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
