## 🚀 What's New in v2.143.0

### Enhanced WASM Deep Inspection (Issue #65)

**New Capability**: Comprehensive bytecode-level WASM analysis for compiler development.

#### Function-Level Analysis
- **Function Signatures**: Complete parameter and return type information
- **Complexity Metrics**: Cyclomatic complexity, instruction counts, branch/loop/call counts
- **Stack Depth Analysis**: Max, average, entry, and exit depths
- **Control Flow Patterns**: Automatic detection and classification
- **Import/Export Analysis**: Full type signatures for FFI boundaries

#### Instruction-Level Details
- **Disassembly**: Full instruction mnemonics and operands
- **Stack Effects**: Push/pop analysis per instruction
- **Cost Estimation**: Execution cost per instruction
- **Category Breakdown**: Control flow, memory ops, numeric ops, etc.

#### Advanced Features
- **Validation Error Tracking**: Context-aware error reporting
- **Suspicious Pattern Detection**:
  - Dead code after unreachable
  - Infinite loops without side effects
  - Excessive stack manipulation
  - Deep control flow nesting
- **Basic Block Construction**: Control flow graph components

#### Implementation
- `bytecode_analyzer.rs` (920 lines) - Module-wide bytecode analysis
- `disassembler.rs` (730 lines) - Instruction-level disassembly
- **Total**: 1,650 lines of production code
- **Tests**: 9 unit tests, all passing
- **Complexity**: CC <3 (well below threshold)

#### Use Cases
- **Ruchy → WASM Compiler Debugging**: Detailed bytecode inspection
- **Optimization Analysis**: Identify inefficient code patterns
- **FFI Validation**: Verify import/export signatures
- **Quality Assurance**: Detect compiler bugs via pattern analysis
