A KEF LSX reached the end of every track and never advanced (#733); its
poll answers were swallowed, so an INFO log could not tell a mute renderer
from one that never reports STOPPED. The DLNA poll now logs a failed
position read, GetTransportInfo faults degrade to the last transport
command instead of failing the whole read, and a RelTime frozen inside the
end guard for five polls without STOPPED counts as end-of-track. A user
pause never counts. Pure helper with unit tests.
