# Release finalizer for the single-process Flutter app (T-393).
#
# Run AFTER the `release vX.Y.Z` commit is in place (version bump + changelog
# move — see .claude/skills/git-commit/SKILL.md "Cutting a release"). It:
#   1. reads the version from pubspec.yaml,
#   2. asserts CHANGELOG.md has a dated section for it (not still Unreleased),
#   3. asserts the working tree is clean,
#   4. runs the full gate (make push-check),
#   5. creates the annotated vX.Y.Z tag if missing — closing the loop that
#      previously left every release since v2.1.0 untagged.
#
# No goreleaser, no sidecar (both dissolved, D-56). Artifact builds are
# `make build-linux` / `make build-macos`. This never pushes — it prints the
# push command for you to run.
#
# Invoke via `make release`, not directly.
