Subject: [PATCH] ci: share one uv sync across jobs, gate tests on
 lint+type-check, sync tag/version on release tags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Uploads the synced .venv as an artifact from a single setup job instead of
re-running uv sync (and re-downloading torch) in every job. Drops the
build/publish job in favor of a lighter job that, on a pushed tag, checks the
tag against the uv project version and — if they differ — bumps the version,
commits it to master, and recreates the tag on the new commit.
