v2.4.0

Added

• OS-repo / Windows auto-tags now publish a GitHub Release too (auto-tag.sh --release). Core releases already become Releases on tag push (release.yml), but the
  OS-repo tags auto-tag.sh cuts in CI were bare — no Releases page entry. A token-pushed
  tag can't trigger a separate on: push: tags workflow (GitHub anti-recursion), so the
  Release is now created in the SAME job: auto-tag.sh --release runs gh release create <tag> --generate-notes right after pushing (idempotent — a no-op if the Release exists;
  a missing gh just leaves the tag, never fails). auto-tag-call.yml gained a release
  input (default true) and passes --release, so every consumer of @v2 gets Releases
  on its next fan-out. Reusable beyond core/ consumers: any repo (e.g. dotfiles-Windows
  on an nvim//starship/ sync) can call the workflow to self-tag-and-release.
