This commit replaces `Arc<Mutex<T>>` with `Rc<RefCell<T>>` for managing shared mutable state within the AST and VM. This change is primarily an internal refactoring to leverage Rust's standard library more effectively for single-threaded scenarios, improving performance by avoiding the overhead of mutexes. The following types and their usage have been updated: - `Environment.global_names` and `Environment.global_values` - `Binder.globals` - `bound_nodes::BoundKind::Lambda.body` (now `Rc<Node>`) - `ast::types::NodeIdentity` (now `Rc<NodeIdentity>`) - `ast::types::Value::List`, `Value::Record`, `Value::Function`, `Value::Object`, `Value::Cell` - `ast::nodes::Scope` and `ast::nodes::Context` - `ast::vm::Closure.function_node` and `Closure.upvalues` - `ast::vm::VM.globals` This change does not alter the external behavior of the library but streamlines internal data management.
