release-notes

Generate release notes for arcfetch:

1. Get the latest tag: git describe --tags --abbrev=0
2. List commits since that tag: git log <tag>..HEAD --oneline
3. Categorize by conventional commit type:
   • feat: - New features
   • fix: - Bug fixes
   • chore: - Maintenance
   • docs: - Documentation
   • refactor: - Code improvements
4. Summarize user-facing changes
5. Note: per releaseRules in package.json, breaking changes trigger a minor bump (not major)
6. Output a formatted summary suitable for a GitHub release
