Walkthrough

This PR refactors bytecode enum handling and casting patterns across the compiler. It replaces explicit u32 casts with standard conversion functions (u32::from()), removes the num_enum dependency, adds Debug derives to bytecode types, macro-generates oparg enum definitions and trait implementations, and removes const qualifiers from eval_ord methods. All changes maintain functional equivalence while modernizing the codebase.

Poem

🐰 Hoppy hops through casting code,
Macros bloom along the road!
Enums dance in templates bright,
From-conversions feel so right! ✨
Debug fields now shine with care,
Refactored with rabbit flair!
