Tauri's built-in DMG styling relies on AppleScript/Finder access which
silently fails on CI (tauri-apps/tauri#1731). Switch to create-dmg tool
which works on GitHub Actions macOS runners.
- Replace Tauri DMG with create-dmg: background image, icon positions,
app-drop-link, codesign, hide-extension
- Regenerate background image at 2x Retina resolution (1320x800)
- Revert tauri.conf.json dmg config (ineffective on CI)
- Reorder steps: Prepare → Notarize DMG → Verify
- Notarize and Verify now use release-assets/ path for DMG
- Add DMG background image with drag-to-install arrow guide
- Configure window size (660x400), app and Applications icon positions
- Center icons horizontally with visual arrow between them
