Migrate Jest → Vitest

  1. Add vitest and create vitest.config.ts (reuse your Vite config if you have one).
  2. Enable globals: true to keep describe/it/expect without imports.
  3. Swap jest.fn() → vi.fn(), jest.mock() → vi.mock(), jest.spyOn → vi.spyOn.
  4. Replace jest.config timers/fake-timers with vi.useFakeTimers().
  5. Run vitest run in CI; drop ts-jest once green.
