- Add tag-push trigger to Release Stable workflow so `git push origin v0.5.9`
auto-triggers the full pipeline (builds, Docker, crates.io, website,
Scoop, AUR, Homebrew, tweet) in one shot
- Add Homebrew Core as downstream job (was manual-only, never auto-triggered)
- Add `workflow_call` to pub-homebrew-core.yml so it can be called from
the stable release workflow
- Skip beta releases on version bump commits (prevents beta/stable race)
- Skip auto crates.io publish when stable tag exists (prevents double-publish)
- Auto-create git tag on manual dispatch so tag always exists for downstream
- Fix cut_release_tag.sh to reference correct workflow name
