📝 Walkthrough

Walkthrough

Added an opt-in spy option to suspended mounting utilities. Object-valued setup results are wrapped with vi.mockObject before exposure through wrapper.setupState. Added CustomRandom components with setup and exposed methods. Added browser and Nuxt tests for spying, mocked random values, button actions, and reactive input updates.
