Description

The current mb8 codegen was written in a rush and wthout enough compiler deisng experience. As a result it is the most hard-to-maintain part of the project crates/mb8c/src/codegen

Contributor guide

Research direction
Study the current codegen in crates/mb8c/src/codegen. Identify architectural flaws, lack of modularity, and hard to maintain patterns. Propose a new design that separates concerns, improves testability, and follows Rust best practices. Consider using intermediate representations (IR) and visitor patterns. Start by documenting the existing behavior and creating a plan for incremental refactoring.
