{"title": "Friendlier greeting and add bye helper", "body": "## Summary\n\n- `greet` now returns `Hello, <name>!` instead of the lowercase `hi <name>`\n- Added a `bye` helper in `greet.ts` that returns `Bye, <name>`\n\n## Testing\n\n- Not run — no test suite or type-check was executed for this change\n- Suggested: type-check `greet.ts` and confirm callers expecting the old `hi <name>` output are updated\n"}
