feat: add automated release notes generation

- Add .github/release.yml to categorize PRs by label in release notes
- Add 'Generate Release Notes' step to manage_release.yml that calls
  the GitHub API to auto-generate notes and injects them into the
  existing draft release via gh release edit --notes-file
