feat: comprehensive development progress

- Pattern matching implementation extended in match_expr.rs
- CLI configuration structured with categorized groups (task recommendation completed)
- Python LLVM builder split into function_lower.py (task recommendation completed)
- parse_box_declaration massive function refactored (task recommendation completed)
- Phase 16 Macro Revolution comprehensive planning and documentation
- Archive legacy phase documentation for clean structure
- HTTP message box improvements and performance optimizations
- MIR builder enhancements and control flow improvements
