Normalize version display across desktop surfaces

[postigodev]

Summary

The desktop app should display the runtime app version consistently across sidebar, topbar, and any other version badges.

Current behavior

This area recently had a mismatch between UI-displayed version values and the actual Tauri bundle version.

Expected outcome

Verify all desktop surfaces use the same runtime version source and stay aligned after future releases.

Scope

• confirm sidebar and topbar stay in sync
• confirm release/version automation does not regress the display
• tighten any remaining version-source inconsistencies

Likely files

• apps/tauri/src/main.ts
• apps/tauri/src/ui/*
• apps/tauri/src-tauri/src/commands.rs
