Add packaging/arch PKGBUILD and Forgejo Actions workflows

- packaging/arch/PKGBUILD: builds and publishes breadpad 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.
