feat(import): prepare native parser rollout

+ * Verify the packaged Electron app ships the Rust native parser binary.
+ *
+ * Usage: node scripts/check-desktop-native.mjs <platform-arch>
+ *   e.g. node scripts/check-desktop-native.mjs darwin-arm64
+ *        node scripts/check-desktop-native.mjs win32-x64-msvc
+ *
+ * Scans apps/desktop/dist for app.asar.unpacked directories and requires
+ * chatlab-parser-native.<platform-arch>.node to exist (non-empty) inside
+ * node_modules/@openchatlab/parser-native. Fails fast so a release without
+ * the native kernel never ships silently.
