fix: minimal TypeScript suppression for vitest mock compatibility

Use @ts-expect-error on vi.mock line only - vitest mock function calls
require spreading unknown[] which TypeScript can't verify as type-safe
without explicit suppression or use of 'any' type. This is a known
limitation of TypeScript with generic mock frameworks.
