- Fix MIR builder to handle built-in Box types (IntegerBox, StringBox, etc.) specially
- Generate MIR with actual constant values instead of ref_new instructions
- Enhance LLVM mock compiler with MIR interpreter foundation
- Add value storage HashMap for future MIR instruction interpretation
This enables proper MIR generation where 'new IntegerBox(42)' becomes '%0 = const 42'
instead of '%0 = ref_new "IntegerBox"'. This is essential for future LLVM code generation.
Example MIR improvement:
Before:
%1 = const "IntegerBox"
%0 = ref_new %1
After:
%0 = const 42
