Andrey 07/16: better inter-scene accuracy may pay off - keep the opportunity.
New curt.pose_freeze_cycle ('Pose freeze conditioning at cycle'): 0 = never
freeze = per-cycle re-derivation (highest accuracy, pre-C3 behavior); 2 =
default (freeze at the post-first-correction measurement); 1 = falsified.
Runtime-selectable - A/B/revert experiments need no rebuild. Wired via
IntersceneLma.setPoseFreezeCycles from leanFitScene.
