Problem

The test helpers could treat a silent single-pane layout or orientation hook as the fingerprint transition for a later split or new-pane action, which left master_stack with intermittent hook-order flakes.

Solution

Teach the shared test helpers to wait for a fingerprint that matches the current window state before and after split/new-pane operations, so later assertions only run after the intended async hook work has actually settled.
