📝 Walkthrough

Walkthrough

This pull request updates test assertion matchers across nine test files in the examples directory to use newer Vitest matcher APIs. The changes replace deprecated or older matcher syntax with their modern equivalents: .toThrowError() to .toThrow(), .toBeCalled() to .toHaveBeenCalled(), .toBeCalledTimes() to .toHaveBeenCalledTimes(), and .toBeCalledWith() to .toHaveBeenCalledWith(). No test logic, control flow, mocking behavior, or test expectations are modified—only the assertion matcher names are updated.
