Reduce desktop frontend bundle size and split large chunk

[postigodev]

Summary

The desktop frontend currently emits a large minified chunk during production build.

Current signal

Vite warns that the main chunk is larger than the recommended size threshold.

Expected outcome

Investigate safe ways to reduce bundle size and/or improve chunk splitting.

Good directions

• identify oversized dependencies
• split code by page or feature where it actually helps
• avoid changes that make the app architecture less clear

Likely files

• apps/tauri/vite.config.*
• apps/tauri/src/*
• package dependency graph
