Release notes written from the commits since the previous tag

- The release page's "What's new" now comes from each commit's subject and body since the
  previous tag, without trailers or any line naming the assistant that helped write them.
- `tools/release.sh notes` writes the notes alone; the release checkout fetches the tags.

+- **Release notes are the commits since the previous tag.** `tools/release.cs` writes "What's new" from each
+  commit's subject (without the `me-web? x.y:` prefix) and body, dropping trailers and any line that mentions Claude;
