v0.5.0

Class Support in WAT/WASM

• Extended WATCodeGenerator to lower class methods to standalone WAT functions.
• Added lowering for constructor-style calls (ClassName(...)) to class __init__ with implicit self.
• Added lowering for class attribute calls (Class.method(...)) and simple instance method calls (obj.method(...)) when object type can be inferred from local assignments.
• Added targeted regressions for class lowering and call lowering in tests/wat_generator_test.py.

Complete Features: Real WASM Executability Gate

• Added tests/complete_features_wasm_execution_test.py to validate all examples/complete_features_*.ml end-to-end:
  • parse multilingual source
  • generate WAT
  • compile WAT to binary WASM
  • write .wat and .wasm artifacts
  • instantiate and execute __main in Wasmtime
• Added Wasmtime fuel metering in this test to bound runtime for heavy complete-feature programs while preserving executable validation.

Unicode Identifier Reliability

• Added deterministic WAT symbol sanitization for generated function/local/parameter identifiers.
• Preserved original exported function names while using WAT-safe internal $symbols.
• Fixed previously failing WAT→WASM compilation paths for non-ASCII identifiers (for example Arabic identifiers in complete-feature examples).

CI Workflow Updates

• Updated .github/workflows/wasm-backends-test.yml to include a primary-job gate that runs complete-feature WAT/WASM artifact + execution validation.
• This adds a dedicated regression barrier for executable WASM quality, not just WAT text validity.

Quality and Stability

• Full test suite status after integration: 1778 passed, 2 skipped.
• Pylint checks on touched files remain clean (10.00/10 in targeted runs).
