gh release create with --target was still creating untagged releases.
The fix is to create and push the git tag explicitly first, then
create the release which will properly attach to the existing tag.
The workflow was broken because it expected a tag to exist but the
documented process never created one. This caused gh release create
to fail with 'untagged' releases.
Changes:
- Workflow now creates the tag using --target flag
- Simplified release creation logic (no retry loops needed)
- Removed confusing comment about 'tag already exists'
This fixes the fundamental issue where the workflow and documented
process were out of sync.
