v0.11.18: DiscStream halt flag — Stop works in dense bad-sector regions

Browse Source 
DiscStream::fill_extents loops internally while the demuxer waits for
enough clean data to emit a PES frame. In a dense bad zone that loop
can run for minutes without returning to the outer read() call, so
the caller's Stop signal never gets serviced until a frame is finally
emitted — which may be very far away.

Add DiscStream::set_halt(Arc<AtomicBool>) — typically wired to
Drive::halt_flag() for unified Stop across drive recovery phases and
stream sector processing. fill_extents checks the flag at the top of
every retry iteration; raising it returns Err(Error::Halted) within
one SCSI round-trip.

No behavior change for callers that don't call set_halt. Unblocks the
architectural fix for the "Stop doesn't stop" bug observed on a
damaged UHD disc.
