Changes

• Added TypeScript 6 compatibility.

  • Added regression coverage for nested object literal matching.

• Fixed overloaded function support in mock proxy types.

  • Restored inferred argument and return types for mocked function properties.
  • Improves typing for overloaded methods on both flat mocks and deep mocks.
  • Adds regression coverage for overloaded method mocks.
