Adds ci/build.sh + ci/bread-ecosystem.rev (pinned to bread-ecosystem
147cfbbf96ae4b171027defa1130d2caddb934b1), points the three release
workflows' build step through it, and adds check.yml as breadarr's first
lint/test gate on feature/fix branches. No ci/deps.txt: verified ort-sys's
build.rs has no system build-time requirements beyond rust/base-devel
(its download-binaries feature is pure-Rust ureq/lzma-rust2/hmac-sha256).
Adds bakery.toml (system_deps verified via ldd + Command::new grep against
breadarrd/src, not guessed) and dev-release.yml/rc-release.yml/release.yml
following bread-ecosystem's current single-trunk + RC-tag CI model. No
GitHub Release step anywhere — this repo has no GitHub mirror.
