Include the streaming-delta fix in the release notes

The v3.13.0...v3.13.1 range also contains 7e31f8c (Fix streaming delta merge for duplicate tool call indexes), a user-visible correction that prevents malformed final tool-call arguments, but this release section lists only the README update. Since 3.13.1 will ship that behavioral fix, add it under a Bug Fixes section so affected users can discover that upgrading resolves the issue.
