stageNodePty received electron-builder's { platform, arch } but unconditionally
copied host build/Release, staging a host binary (e.g. macOS Mach-O) for a
foreign target (e.g. linux-arm64). The fallback rebuild also didn't pass the
target arch to electron-rebuild.
Now:
- build/Release is only staged when target platform+arch match the host
- cross-platform targets with no matching prebuild fail closed
- same-platform different-arch rebuild passes --arch to electron-rebuild
- post-staging validation reads .node magic bytes (ELF/Mach-O/PE) and rejects
any binary whose platform doesn't match the target
Adds stageNodePtyInto() (testable core) and classifyNativeBinary() (pure),
plus 11 regression tests covering the cross-target scenarios.
