Read changes.md and write a release note to release-note.md.

Follow the style and rules defined in prompts/release-note.md exactly.

Steps:

1. Read prompts/release-note.md for formatting rules
2. Read package.json to get the current version
3. Read changes.md for current change entries
4. Read release-note.md for existing release notes
5. Transform all changes.md entries into the release note format
6. Write ## <version> section to release-note.md
   • If the top section already has the same version, replace that section
   • If the top section has a different version, clear the entire file and write only the new version section
7. Clear changes.md contents (keep the file, empty the content)
