breadcrumbs had a watch subcommand meant to run continuously but no
systemd unit anywhere, so bakery installs never actually started it -
Wi-Fi profile config in bos-settings had no daemon consuming it.
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.
