# Build + publish versioned Windows and Linux release bundles when the version
# in pubspec.yaml changes on main. The `version` job only proceeds when the
# v<version> tag doesn't already exist, so an unrelated pubspec edit is a no-op.
#
# FIRST CUT — neither build has run in CI yet (Windows has never been built at
# all), so expect to iterate on these from the first run's logs. The repo's own
# `make` targets are the build contract (gen-build-info + clide-cli + flutter
# build, all wired in `make build`).
