ComfyUI version listing + nightly current fix (#2334)

* Improve comfyui version listing

* Fix ComfyUI semver selection and stable update

* Fix nightly current detection on default branch

* Fix: use tag_ref.name explicitly and cache get_remote_name result

- Use tag_ref.name instead of tag_ref object for checkout
- Cache get_remote_name() result to avoid duplicate calls
