## Summary by CodeRabbit

* **Chores**
* Added CI workflow to build WebAssembly targets with optimized caching
on both hosted and self-hosted runners, improving build consistency and
speed.
* **Tests**
* Expanded automated checks to include WebAssembly build verification
for multiple modules, increasing coverage and early detection of build
issues.
