@claude claude / Claude Code Review

Same getPrototype().getObject() null-deref pattern remains in napi.cpp (pre-existing)

Heads-up (pre-existing, not introduced here): the same `getPrototype(globalObject).getObject()` pattern without an exception check still exists at `src/bun.js/bindings/napi.cpp:1837` in `napi_get_all_property_names`. A throwing Proxy `getPrototypeOf`/`getOwnPropertyDescriptor` trap on the prototype chain will cause the same null deref there when called with `napi_key_include_prototypes` + a descriptor filter — might be worth a follow-up since it's the identical bug class.
