Subject: [PATCH] feat(stop): the post-upload readiness poll waits via pause
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

WallClock's wait between TEST UNIT READY polls is now the transport's
cancellable pause (stop-design-v5 §2.3), so a Stop during the poll ends it
at once. The refusal is the dead-bus shape; libfreemkv's Drive::init
reclassifies it as Halted (ST-L2).
