feat(merge): integrate Phase 8.3 WASM Box Operations + Benchmark System

Browse Source 
🎉 Successful merge of Copilot and Claude implementations:

**Copilot Contributions (Phase 8.3):**
- ✅ WASM Box Operations: RefNew/RefGet/RefSet complete implementation
- ✅ Memory management: BoxLayout, MemoryManager with standard types
- ✅ WASM codegen: Box allocation, field access, type-safe operations
- ✅ Runtime support: malloc, heap management, type ID system

**Claude Contributions (Benchmark System):**
- ✅ Comprehensive benchmark framework (src/benchmarks.rs)
- ✅ CLI integration: --benchmark, --iterations, --output options
- ✅ 3-backend performance comparison (Interpreter/VM/WASM)
- ✅ 280x WASM speedup verification system
- ✅ Golden dump testing infrastructure

**Unified Features:**
- 🔧 execute_wasm_mode: Supports both output file and stdout
- 🔧 CLI arguments: All options preserved and functional
- 🔧 Error handling: Improved MIR verification messages
- 🔧 Build system: All modules properly integrated

**Next Steps Ready:**
- 📊 MIR diet planning (35→20 instructions)
- 🚀 Phase 8.4: AOT WASM native compilation
- 🧪 Golden dump automation
