fix(#171): R5-V3 — bind sticky melee (StickyManager live) + real arrival radii

Group-melee interpenetration + facing drift: the R5-V1-ported
StickyManager/PositionManager were Core-only — the StickTo/Unstick seams
were unbound and every arrival radius was 0, so ACE's Sticky|UseSpheres
melee chases closed ~one body-radius too deep and froze at stale arrival
poses until the next wire re-arm. Retires TS-39.

Wiring (anchors re-verified against the named decomp this session):
- EntityPhysicsHost owns a PositionManager; HandleUpdateTarget fans
  MoveToManager then PositionManager (CPhysicsObj::HandleUpdateTarget
  0x00512bc0 order).
- Seams bound remote + player: MoveToManager.StickTo (BeginNextNode
  sticky arrival @0x00529d3a), Unstick (PerformMovement head), and
  MotionInterpreter.UnstickFromObject (UM funnel head, 0x0050eaea).
- AdjustOffset at the retail UpdatePositionInternal slot (@0x00512d0e):
  NPC branch composes pre-sweep (steer is swept by ResolveWithTransition);
  remote-player branch chains the combiner offset through the shared
  delta frame (the interp stage) so sticky OVERWRITES when armed
  (0x00555430 assigns m_fOrigin, not accumulates); player inside the
  30 Hz physics quantum before UpdatePhysicsInternal.
- UseTime (the 1 s lease watchdog) at the UpdateObjectInternal tail
  (@0x005159b3): unconditional per remote; player gated on the physics
  tick (retail's MinQuantum gate skips UseTime too).
- Real setup cylsphere radii (CPartArray::GetRadius/GetHeight
  0x005180a0/0x005180b0 = setup radius/height x ObjScale from the spawn
  record): own via EnsureRemoteMotionBindings + player wiring; target via
  RouteServerMoveTo AND the speculative use-walk install (retail resolves
  the target PartArray at EVERY MoveToObject site — ACE PhysicsObj.cs:951).
- Teardown parity: exit_world (0x00514e60) UnStick + ClearTarget before
  the ExitWorld notify; player teleport fires teleport_hook's tail
  (UnStick in SetPosition + EntityPhysicsHost.NotifyTeleported =
  ClearTarget + NotifyVoyeurOfEvent(Teleported) @0x00514f1b) so mobs
  stuck to the player drop their sticks on a recall.
- SERVERVEL arbitration also yields to a stuck entity (same starvation
  class as the #170 fix — sticky owns the between-snap translation).
- StickyManager.UseTime aligned to retail's strict > deadline
  (0x00555626; ACE >): two V1 tests had pinned the >= edge — corrected.

Register: TS-39 deleted; TS-41 narrowed (stickyArmed gate); TS-43 added
(remote teleport_hook gap — self-corrects within the 1 s lease); AP-23
narrowed (real radii at the speculative site; only the use-radius
buckets remain invented).

Conformance: 2 new full-stack sticky scenarios in
RemoteChaseEndToEndHarnessTests (arrive -> stick -> strafing-target
gap+facing track -> lease expiry; unstick-on-rearm -> re-stick).
Full suite 4038 green.

Pre-commit adversarial diff review (3 lenses + per-finding refuters)
confirmed and fixed 4 findings: ObjScale-dead radius read, player
UseTime order inversion, missing teleport voyeur notify, speculative-
site radius asymmetry.

Awaiting the user visual gate: pack melee side-by-side vs retail
(attackers reshuffle + keep facing; some overlap is ACE-server-side).

 Add a `PositionManager` to each host. Bind `MoveToManager.StickTo →
 host.PositionManager.StickTo`, `MoveToManager.Unstick → host.PositionManager.UnStick`.
 The load-bearing part: integrate `host.PositionManager.AdjustOffset(deltaFrame,
