by chenranfix: require confirmed stop before SC rotation
Route pending turns through MOVE_NSTOP and MOTION_STOP before entering MOVE_PREPARE. Remove rotation recovery shortcuts and gate published rotation activation to preparation.
Advance the outgoing SSEP segment during a confirmed stop, including start rotations propagated from an end-point request. Add FSM, publication, and handoff regression coverage.
