Adds ci/build.sh + ci/bread-ecosystem.rev (pinned to bread-ecosystem
147cfbb) following the pattern proven in breadpad, so releases build
inside the shared pinned container instead of installing toolchain
deps directly on the bare runner. Routes dev/rc/release build+test
steps through it and adds a check.yml for fast clippy/test feedback
on feature/fix branches. No ci/deps.txt — breadcrumbs' dependencies
(clap/serde/toml/serde_json) are pure Rust with no system library
needs; nmcli/tailscale/sudo/xdg-open are shelled out to, not linked.
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.
