Testing claude for reviewing NodeJS Class/Object support: #343

[josead]

Implement class and object interfaces for the Node.js loader:

• Add struct definitions for loader_impl_node_class and loader_impl_node_object
• Implement class interface callbacks (create, constructor, static_get, static_set, static_invoke, static_await, destroy)
• Implement object interface callbacks (create, get, set, method_invoke, method_await, destructor, destroy)
• Update value conversion functions for TYPE_CLASS and TYPE_OBJECT
• Add class discovery in bootstrap.js using espree AST parsing:
  • node_loader_trampoline_is_class() for ES6 class detection
  • node_loader_trampoline_discover_klass() for class metadata extraction
  • Support for static/instance methods and attributes
  • Constructor signature detection
• Update discover function to handle classes alongside functions

This implementation follows the pattern established by py_loader and rb_loader for class/object support.
