NeilandOrca 15a6ebaf77 test(terminal): capture visual proof of the STA-2694 stale paint ...

The earlier screenshot oracles were blind because they compared a revealed pane
against a repaired one and both ran the same repaint code. Capturing the defect
directly works instead, because the mechanism is self-preserving: while
synchronizedOutput is latched, refreshRows returns before reaching the renderer,
so a compositor frame just re-composites the existing canvas texture and the
stale pixels survive the screenshot rather than being healed by it.

Latch a frame, write a full new frame the pane cannot paint, and capture. The
screenshot comes back byte-identical to the pre-hide one while the buffer holds
the new frame — the buffer/screen divergence users report — and differs after
the reveal repaint runs. Asserts both halves, so it fails if either the defect
stops reproducing or the fix stops repairing it.
