Introduces a `Scope` struct for dynamic scope management and a `Context` struct to hold the current scope. Implements a basic standard library with arithmetic operations and a greater-than comparison. Modifies `Node::eval` to handle identifiers by resolving them within the current scope and `Call` nodes for function execution. Updates the parser to use `Context::new()` for evaluating vector elements, ensuring a fresh scope. Enhances the main loop to handle potential runtime errors during evaluation.
