deps-update

Step 1: Snapshot Current State

Before changing anything:

1. Fetch upstream and check out a clean base:

   git fetch upstream
   git checkout upstream/main
   git checkout -b chore/deps-update
   

   If the working tree has uncommitted changes, stop and tell the user to commit or stash first. Dependency updates must land on a clean tree.
2. Run uv lock --check to confirm the lock file is currently consistent
3. Run uv run python --version to record the Python version
