This is a massive milestone! Seeing that perfectly structured JSON output
means the front-end of your compiler is fully operational. The Lexer and
Parser have successfully transformed unstructured text into a rigorous,
traversable data structure.

We are now ready for the final piece of the compilation pipeline: the Code
Generator (Codegen).

The Codegen uses a standard technique called the Visitor Pattern. It walks
through the AST node by node, converting logical statements (CallExpression,
Literal) into the 32-bit binary instructions (SET_INT, ECALL
