Direzione di ricerca

Start by reviewing the linked CI run and the snapshot creation path shown in the stack trace, especially node::SnapshotBuilder::CreateSnapshot. Reproduce with V8 15.9.23 by running the affected test-snapshot-* tests, then trace why the global handle is not serialized. Done means the snapshot tests and the named inspect and benchmark tests complete without the fatal error.
