What to build

Extract method/function parameter types and return types from source code and display them in class diagram boxes. Currently methods show as +method_name() without signatures. Should show +method_name(param: Type) -> ReturnType.

Applies to both Rust and Python extractors. For Rust: parse function_item parameters. For Python: parse typed_parameter in method definitions.

Acceptance criteria

Rust extractor captures method parameter types and return types
Python extractor captures method parameter types and return types
Mermaid renderer shows method signatures in class boxes
ASCII renderer shows method signatures
Tests for both languages verify parameter extraction
Existing tests still pass

Blocked by

None - can start immediately
