Sync uv.lock with relaxed msgpack/tornado caps

Regenerate uv.lock so uv sync --locked matches the pyproject.toml cap

relaxation (msgpack<=1.2.1, tornado<=6.5.7). Only the requires-dist

specifiers change; no resolved versions move (1.1.2/6.5.5 still satisfy

the widened caps), keeping the fork diff minimal.
