Release notes preview: keep this section in sync with the package CHANGELOG.md. Publish reads the merged CHANGELOG via release.yml, not this PR description — keep them aligned anyway so the PR stays an accurate historical record for reviewers and anyone returning later.

When the release changes are finalized, run:

@release-bot apply

Merge only after the curated release-notes check passes.

If new relevant entries appear after applying, draft again and then re-apply:

@release-bot draft

@release-bot apply

To ship without curated notes, add the release: dangerously skip curated notes label. That is the only way to skip the curated-notes merge gate — use it only when you intentionally want the generated changelog as-is, without maintainer polish.
