whuppi/ci 2.0.1

• Fixed the release-tool action swallowing every output release.sh writes.
  The v2.0.0 move from a workspace checkout to a composite action lost the
  output plumbing: composite actions only expose inner-step outputs through an
  explicit outputs: mapping, and the action had none. The gate would decide
  should_run=true, the caller's steps.<id>.outputs.should_run read back
  empty, and every downstream job (discover, git-install-note, publish)
  skipped — a release run that goes green while releasing nothing. The action
  now maps should_run, version, tag, and has_release outward.
