fix: use --frozen instead of --locked in release workflow (#3140)

* fix: regenerate uv.lock after version bump in release script

When the release script bumps the version in pyproject.toml, it needs
to also regenerate the uv.lock file. Otherwise the lockfile becomes
out of sync and `uv sync --locked` fails in CI with:
"The lockfile at uv.lock needs to be updated"

* fix: use --frozen instead of --locked in release workflow

The release script bumps the version in pyproject.toml, which causes
the lockfile to be out of sync (uv includes the package's own version
in the lockfile). Using --frozen skips the lockfile freshness check
while still using pinned dependency versions.
