Toward a truer mirror (user: peer 'hesitates/skips on accel/decel, master has
smoother transitions'). The body channel FOLLOWS the master's replicated STATE
(96a896a) but its CADENCE (bodyCycleSpeed) is still slewed LOCALLY toward the
replicated commanded speed -- which drifts from the master's actual cadence, so
the animation phase wanders until a record snaps it (the hesitation).
FIX (replicant-gated, single-player untouched): peerMirrorSpeed member = the
actual replicated ground speed (|updateVelocity|, set in the peer branch); the
body channel walk (6/7) + reverse (0xc/0xd) cases override bodyCycleSpeed with
it (clamped to the state's band) right before the clip advance, so the peer's
clip advances at the master's REAL rate instead of a locally-drifting slew.
peerMirrorSpeed = -1 on the master/single-player -> the authentic slew runs.
BT_NO_MIRROR_CAD / BT_PEER_LEGCH revert.
Verified autonomous (through-zero sweep): no crash, body channel advances forward
(back-steps ~0), feet track (position ratio 1.05, maxStep 1.68u). Perceived
smoothness is the visual test (harness saturates).
