* feat: add support for named parameters in method calls

Implements named parameter syntax (param=value) in DSL method calls while maintaining backward compatibility with positional parameters.

Features:
- Grammar extension: Added namedParameter rule to ANTLR grammar
- Parser types: Extended interfaces to support both named and positional parameters
- Rendering: Enhanced SignatureText.ts with formatParameters helper
- Mixed support: Allows mixing positional and named parameters
- Backward compatibility: All existing syntax continues to work

Examples:
- A.method(userId=123, name="John")
- B.create(type="User", active=true)
- C.mixedCall("first", second=456, "third")
