Note

Low Risk
Primarily dependency/version bumps and lockfile regen; behavior changes are limited to whatever upstream changes come with the updated packages (notably vws-python).

Overview
Updates dependency pins, most notably bumping the dev documentation tool doccmd to 2026.3.1 and regenerating uv.lock accordingly.

Also refreshes several related package versions in the lock/pins (including ruff, ty, sybil-extras with new parser deps, and vws-python), with no application code changes.
