fix(release): remove mac runner dependency for CLI binary builds

- switch `release-cli` binary matrix to cross-compile on `ubuntu-latest`
- build Linux/Windows/macOS artifacts via Bun `--target` values
- avoid unsupported `macos-13-us-default` runner configuration failures
- keep artifact naming and release attachment behavior unchanged
