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. One concrete likely contributor is apps/tauri/src/icons.ts, which imports both createIcons and the entire icons map from lucide, then passes the full collection into createIcons().

Expected outcome

Reduce the desktop bundle size without making the architecture harder to understand.

Recommended first step

Replace the full Lucide icon-map import with an explicit icon registry containing only the icons Sendo actually uses, then measure the production bundle again before adding manual chunking.

Follow-up directions if needed

• split code by page or feature only where measurements justify it
• inspect remaining oversized dependencies
• keep chunk boundaries aligned with real architectural boundaries

Constraints

• measure before and after
• do not add manual chunking solely to silence Vite warnings
• avoid abstractions that make icon usage or page loading harder to reason about

Likely files

• apps/tauri/src/icons.ts
• apps/tauri/vite.config.ts
• apps/tauri/src/*
