Plugin Hook Filtering

What: Function-type hooks are now filtered out when serializing plugin hooks.

Details:

  • Function Er2() at line 472146 adds .filter((Q) => Q.type !== "function") to hook serialization
  • Prevents function-type hooks from being included in serialized plugin configurations
  • Evidence: Er2() at line 472146-472151

Why it matters: Function-type hooks cannot be serialized to JSON, so filtering them prevents serialization errors.
