## Summary by CodeRabbit

* **Chores**
* Improved Electron build to trim unused locale files on macOS, Windows,
and Linux while always preserving English fallbacks; added post-build
cleanup and stricter packaging ignore rules to exclude tests, examples,
scripts, docs, README, and build metadata.
* **Style**
  * Reformatted a TypeScript type annotation for consistency.
