feat(R4-V4): REMOTE cutover - per-remote MoveToManager; RemoteMoveToDriver + PlanMoveToStart DELETED (closes M1-remote, M4/M5/M6/M8-remote; retires AD-8, AD-9, AP-8, AP-9)

Every remote's server-directed movement now runs the verbatim retail
MoveToManager. EnsureRemoteMotionBindings constructs it per remote with
the full V2 seam set (position/heading/velocity providers, the P4
TargetTracker adapter via setTarget/clearTarget storing the tracked
guid on RemoteMotion) and binds InterruptCurrentMovement ->
CancelMoveTo(0x36) - the retail interrupt chain (TS-36 remote side).

UM routing is retail's unpack_movement dispatch (0x00524440): the
head-interrupt + unstick fire for EVERY movement type, then mt 6/7
build MovementParameters.FromWire(raw bitfield - now surfaced by the
parser) + a MovementStruct (mt 6 resolves the target guid against the
entity table, degrading to MoveToPosition at the wire origin per the
plan's 2f; my_run_rate written from MoveToRunRate per @300603) ->
MoveTo.PerformMovement; mt 8/9 likewise via FromWireTurnTo; ONLY mt 0
flows through the interpreted funnel (the PlanMoveToStart seed is
DELETED - retail never routes MoveTo types through the interpreted
state copy).

Per tick: the P4 tracker feeds HandleUpdateTarget(Ok/ExitWorld) from
the live entity table, then UseTime runs the manager's steering/
arrival/fail handlers, then apply_current_movement recomputes velocity
- the same shape ordinary locomotion uses. The legacy driver branches,
the stale-destination timer, and the ClampApproachVelocity band-aid
are gone; arrival now uses retail cylinder distance (watch melee-range
stop distance in the visual pass).

DELETED: RemoteMoveToDriver.cs + its tests (OriginToWorld relocated
verbatim to MoveToMath; the B.6 auto-walk's two surviving constants
inlined into PlayerMovementController, dying with it in V5);
ServerControlledLocomotion.PlanMoveToStart + tests (PlanFromVelocity
survives - new AP-80 row); the RemoteMotion MoveTo capture fields.
Registers: AD-8/AD-9/AP-8/AP-9 retired; AP-79 (TargetTracker adapter,
retire R5) + AP-80 added.

Full suite green: 3,948 passed. Live smoke launched - NPC
chase/wander behavior pending user verification (recorded in the
session handoff).
