- bump version to 2.5.0 (2.4.3 was the 2023 gem release, tagged on the
  pre-ISC .imp corpus; the version is consumed)
- map-artifact: create the release if missing before uploading assets
- remove legacy release.yml: it checks out the interscript/interscript
  monorepo, not this repo — it can never release this tree; the tag
  would fail on a broken workflow
