name: Release Skill

# Tag-driven per-skill release.
#
#   git tag web-design-engineer-v1.2.0
#   git push origin web-design-engineer-v1.2.0
#
# This workflow:
#   1. Parses the tag to extract <skill> and <version>.
#   2. Validates the manifest version matches the tag (no drift) and packs
#      skills/<skill>/ into <skill>-<version>.zip + .sha256 via `npm run pack`.
#   3. Generates release notes from `git log` since the previous tag of this
#      same skill (falls back to all-history on the first release).
#   4. Creates a GitHub Release with the zip + sha256 attached.
#   5. Re-renders the inline `Download v<version> .zip` link in localized
#      READMEs via `npm run readme:sync` and pushes the change back to the
#      default branch.
#
# See CONTRIBUTING.md for the full release flow (and `cut-release.mjs` which
# automates the maintainer-side bump + tag + push).

      # after a char class is a literal `+`, NOT "one or more". So we use
      # a permissive `*-v*` here and let the parse step below validate the
      # exact `<skill>-v<MAJOR>.<MINOR>.<PATCH>[-prerelease]` shape.
