feat(joinir): Phase 224-C - MethodCallLowerer with argument support

Browse Source 
- Add StringIndexOf to CoreMethodId (arity=1, return IntegerBox)
- Extend MethodCallLowerer to handle methods with arguments
- Add arity checking against CoreMethodId metadata
- Recursive argument lowering via lower_value_expression
- 8 unit tests PASS (indexOf, substring, arity mismatch)
