Objetivo: Run a real vitest suite with no network, and know which of its matchers disagree with each other HOW

run the suite with the network off on node:22-alpine, through vitest's node API
assert five tests were collected and every one of them passed rather than skipped
assert toEqual ignores an own property whose value is undefined, and toStrictEqual reports it
assert toStrictEqual also rejects a class instance whose fields toEqual accepts
assert advanceTimersByTime fires a setTimeout without waiting, and moves the faked Date by the same amount
assert a cancelled timer never fires however far the clock is advanced
assert advanceTimersByTime does not flush the microtask a timer's resolve queues, and advanceTimersByTimeAsync does
assert await expect(...).rejects reports the rejection, while the bare call compares nothing and returns a thenable that is not a Promise
assert toThrow sees no error from an async function, because the failure is a rejected promise and not a throw
assert toBe is Object.is: NaN matches NaN, while -0 matches neither toBe(0) nor toEqual(0)
run a second suite that forgets the await on two false .rejects assertions, and assert that run reports two tests and leaves process.exitCode at 1
assert the forgotten await in a sync test function fails that test, carrying the real rejection message in the error
assert the forgotten await in an async test function leaves the test reported as passed while the failure becomes the run's one unhandled error
