fix: harden the Electron 43 release runtime

Upgrade Electron, electron-builder, and electron-updater to patched versions, align the supported Node.js toolchain, and preserve secure file drops through the context-isolated webUtils bridge.

Cover the Electron 43 file-path migration with a real temporary-file drag-and-drop regression test and retain zero-vulnerability lockfile resolution.
