Pull request overview
This pull request adds support for projectable method overloads by including parameter type information in the generated class names. Previously, methods with the same name but different parameter types would cause name collisions in the generated code. The solution encodes parameter types into the generated class name (e.g., _Method_P0_int_P1_string) to make each overload unique.
Changes:
- Modified the source generator to collect parameter type names and include them in generated class names using Roslyn's
SymbolDisplayFormat.FullyQualifiedFormat - Updated the runtime resolver to reconstruct parameter type names from reflection and match them to generated classes
- Added comprehensive tests for method overloads with different parameter types and counts
