monty-go: Pure-Go wrapper for Pydantic's Monty Python Interpreter

Monty-go is a pure-Go wrapper for executing Python code safely within Go applications by compiling Pydantic's Monty Python interpreter to WebAssembly. It enables LLM agents to write multi-step Python code that calls Go functions, which pause and resume execution, eliminating the need for containers, CGO, or subprocesses while providing sub-millisecond startup times.
