[desktop] optimise cold start

[undg]

Recommended Optimizations

• Reduce Locale Files (High Impact)
  The locales directory is 44 MB and likely contains translations for 100+ languages you don't need. You can configure electron-builder to include only the locales you need.
• Enable ASAR Compression (Medium Impact)
  Currently your app.asar is not explicitly configured for compression. ASAR packing can improve startup time by reducing I/O operations.

Optimize Electron-Builder Configuration (Medium Impact)

• Enable compression
• Remove unused Chromium features
• Configure AppImage compression settings

Code Optimization (Low-Medium Impact)

• Remove preload script since you're not using it
• The window shows after loading a remote URL which adds network latency

Use V8 Snapshot (Advanced)

• Create a V8 snapshot of your app to reduce JavaScript parsing time on startup.
