GitHub Actions self-hosted runners need per-repo registration on a
personal account; Forgejo Actions' runner already serves every repo
with zero setup. Moves release publishing there (dl.breadway.dev stays
the primary bakery target; GitHub release upload is kept as the
fallback via an explicit token, since Forgejo Actions has no ambient
GITHUB_TOKEN) and adds a mirror workflow to keep GitHub in sync
automatically.
- .forgejo/workflows/mirror.yml: mirrors every push/tag to GitHub
- .forgejo/workflows/package.yml: builds PKGBUILD on tag and publishes
the bread package to the Forgejo Arch registry (distrib=breadway)
Requires two Forgejo secrets:
GITHUB_MIRROR_TOKEN — GitHub PAT with repo push scope
FORGEJO_TOKEN — Forgejo token with package:write scope
