+// afterPack hook for electron-builder
+// Removes host-compiled native module artifacts so cross-platform builds
+// use the correct prebuilt binaries from the `prebuilds/` directory.
+//
+// Why this is needed:
+//   `electron-rebuild` (postinstall) compiles uiohook-napi for the BUILD
+//   machine (e.g. macOS arm64), placing the binary in `build/Release/`.
+//   `node-gyp-build` checks `build/Release/` BEFORE `prebuilds/{platform}/`,
+//   so Windows/Linux packages would load the macOS binary and crash.
+//
+// What this does:
+//   1. Removes `build/`, `build.bak/`, `bin/` dirs (host-compiled artifacts)
+//   2. Strips prebuilts for platforms other than the target
