Ports breadpaper onto bread-ecosystem's shared, pinned Arch build
image/script instead of installing toolchain/libraries directly on the
bare self-hosted runner. Follows the pattern proven in breadpad:
ci/build.sh clones bread-ecosystem pinned to the sha in
ci/bread-ecosystem.rev and delegates to its ci/build.sh.
breadpaper needs nothing beyond the shared image's base package set
(only clap/anyhow as deps, no image-processing or GTK crates), so no
ci/deps.txt is added.
Also adds check.yml: clippy + test on feature/**/fix/** pushes, as a
fast pre-release-build signal, matching breadpaper's own build/test
flags (--release --locked, no --workspace since this isn't a
workspace).
Replaces the dev/beta branch split with one trunk (main): dev-track
builds still publish on every push, but the beta track now publishes
from a vX.Y.Z-rc.N prerelease tag instead of a separately-maintained
beta branch. Removes the branch nobody reliably kept in sync.
bakery already fully covers what the PKGBUILD provided (binary, systemd
--user service where applicable, dependency declarations) except a LICENSE
copy, which bakery.toml's new license_file field now closes. Removes
packaging/arch/ and .forgejo/workflows/package.yml; adds the LICENSE
artifact to each release/dev-release/beta-release workflow's prepare
step. Not pacman-installed inside BOS today (BOS already consumes these
apps exclusively via build-local.sh's skel-staging), so this only removes
the option to `pacman -S` outside of BOS/bakery.
Cargo.toml can drift stale relative to the actual last release (observed
on breadbox/breadpad/breadcrumbs/breadpaper), which made the auto-bumped
dev version sort as OLDER than what's already installed — bakery's semver
check correctly refused those "updates". Deriving the base version from
git ls-remote --tags instead is self-healing regardless of Cargo.toml
drift, with a Cargo.toml fallback only for a repo with no tags yet.
The fixed /tmp/bread-ecosystem-ci path races when multiple repos' dev/beta
workflows run close together on the same self-hosted runner — one job's
rm -rf/clone can stomp another's in-progress checkout, causing the
regenerate-index step to fail intermittently. Switch to mktemp -d.
Adds dev-release.yml (publishes on every push to dev) and beta-release.yml
(publishes on a beta-v* tag), mirroring the pattern landing in
bread-ecosystem/bread. See bread-ecosystem/docs/release-channels.md for
the three-track policy.
