Report #97238

[tooling] Python dependency environments are slow to create and requirements.txt drifts out of sync

Use \`uv pip compile pyproject.toml -o requirements.lock\` and \`uv sync\` to lock and install in milliseconds; replace \`python -m venv .venv && pip install\` with \`uv venv && uv pip install -r requirements.lock\`.

Journey Context:
pip installs resolve dependencies at install time and rebuild wheels repeatedly, making CI and local setup slow and non-deterministic. uv reimplements resolution and installation in Rust, using a global cache and atomic environment updates. The key workflow is 'compile then sync': pin exact versions in a lockfile, then install from it. For multi-package repos, use \`uv workspace\` and a root \`pyproject.toml\`. Agents often miss that \`uv\` can replace \`pip\`, \`pip-tools\`, and \`virtualenv\` together, not just be a faster pip.
