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.
- packaging/arch/PKGBUILD: builds and publishes breadbox to [breadway] repo
- .forgejo/workflows/mirror.yml: mirrors every push/tag to GitHub
- .forgejo/workflows/package.yml: builds on tag, publishes to Forgejo registry
Requires FORGEJO_TOKEN and GITHUB_MIRROR_TOKEN secrets in Forgejo.
