At every poseSequencePass start, explicitly drop the per-sequence GPU task
template and the DP seeding key, re-arm the scene-0 DP oracle, and return the
device image-set ring to set 0. A back-to-back rerun in the same JVM now seeds
identically to a fresh launch (restores the simple byte-identity gate; fresh
starts were already bit-exact, reruns wobbled 0.0024 px from carried-over warm
state - the previous run's last D5 overlap leaves an arbitrary active set while
the new run's ring bookkeeping assumes set 0), and a (re)started production RT
sequence never inherits stale resident state.
