Write the pull request for the current branch: the merge mode (squash or rebase), a title that is the changelog line when squashed, and a description per the Pull requests rules, all checked with tools/commit-lint. Also writes GitHub issues from two templates: a feature as a story with a definition of done, a bug with steps to reproduce and expected and actual behaviour. Use when asked to write, draft or open a PR or an issue, to produce a PR title or squash message, or to choose how to merge a PR.
Turn the generated release notes into the ones a release publishes. Generates the entries with script/release-notes, then merges entries that describe one change, drops work that never shipped and internal changes, rewrites entries into one consistent voice, and writes the Highlights and Upgrading sections, with an audit that accounts for every generated entry. Use before tagging a release, or when asked to draft, clean up or review release notes.
