ci: add release workflow (manual dispatch: cz bump + tag + Gitea release)

Cutting a release is now a workflow, not a local command. Uses uv/commitizen (actions/setup-python is broken on the current runners). Supports auto-detect or forced increment, and a dry_run mode.

+# updates CHANGELOG.md, tags vX.Y.Z, pushes both, and creates a Gitea release.
