fix(desktop): restore Electron binary before macOS pack rename (salvage #38673)

Browse source 
electron-builder 26.8.x can stage an Electron.app without its
Contents/MacOS/Electron binary, then fail renaming it to Hermes:

    ENOENT: no such file or directory, rename .../MacOS/Electron -> .../MacOS/Hermes

This breaks `npm run pack` and the installer desktop stage before a
launchable Hermes.app exists.

- Point build.electronDist at the already-installed Electron dist so
  electron-builder reuses it instead of re-unpacking from cache.
- Add a darwin-only prebuilder patch that restores the missing main
  binary from the runtime dist before the rename. Idempotent (marker
  guard), soft-fails on shape mismatch, survives node_modules reinstall.
