chore(#170): strip the temp probes, close the issue (user visual gate PASSED)

Gate result: user side-by-side vs retail — "looks good, as close to retail
now as I can see". Telemetry from the gate session (launch-170-gate2.log):
BeginMoveForward ~1:1 with MoveToObject arms for every chasing creature
(pre-fix capture was 16:1), ZERO "SERVERVEL skips UseTime while armed"
occurrences, pending_motions depth 1 at last sample.

Stripped per the #170 close-out plan: s_mvtoDiag + all [mvto] prints
(MoveToManager), s_drainDiag + [drain]/[drainq] (MotionInterpreter), the
[npc-tick] branch prints and the "UM actions" inbound-action dump
(GameWindow). The durable ACDREAM_DUMP_MOTION family stays. The
RemoteChaseEndToEndHarnessTests + RemoteChaseDrainBisectTests conformance
suites stay as the permanent regression net for this pipeline.

ISSUES: #170 -> DONE + Recently-closed entry (fix SHAs 427332ac, d2ccc80e,
1051fc83). Memory topic + index flipped to CLOSED.

+## #170 — Remote creature chase+attack renders wrong vs retail (glide, run not sustained)
+
+**Status:** DONE (2026-07-04, user visual gate passed — "as close to retail now as
+I can see"). Three-fix arc: `427332ac` deleted the per-frame
+`apply_current_movement` re-dispatch that flooded `pending_motions` to ~1.3M
+(chase turn permanently blocked → slide); `d2ccc80e` refreshed remote body
+velocity from `get_state_velocity`; `1051fc83` fixed the residual — the
+SERVERVEL per-tick branch skipped `MoveToManager.UseTime` for any UP-receiving
+NPC, starving the armed moveto for the whole server-side chase (funnel 16 arms →
+1 run install; retail runs `MovementManager::UseTime` unconditionally,
+`UpdateObjectInternal` 0x005156b0 @0x00515998) — an armed moveto now always takes
+the MOVETO leg. The intermediate "Ready drain too slow" hypothesis was DISPROVEN
+by the full-stack offline harness (`RemoteChaseEndToEndHarnessTests` +
+`RemoteChaseDrainBisectTests`, kept as conformance). Register: TS-41 narrowed,
+TS-42 added (one-frame drain-order divergence, R6). Gate telemetry
+(launch-170-gate2.log): installs ≈ arms for every creature, zero armed-moveto
