test(render): add the repeat-run connected gate; record V4c/V4d re-land conditions

The V4c blank-world regression was intermittent - roughly one launch in three at the worst location, zero in seven at the parent - so a single connected capture passes the broken binary most of the time and gates nothing. The new gate runs N full connect-teleloc-render-screenshot cycles with graceful logout and a per-run verdict by screenshot content size, refuses to start if a client is already using the shared test account, and pins the teleloc because the failure rate is location-sensitive. Ten clean runs bound a one-in-three defect below roughly four percent.

Campaign doc 5.5 records the revert evidence and the binding re-land conditions: the GL ring write path moves to mapped unsynchronized writes, and V4c/V4d re-land only at 10/10 rendered plus a passing offline gate.

+.SYNOPSIS
+    Campaign V repeat-run connected gate: N full connect-render-screenshot cycles
+    against the local ACE server, with a pass/fail verdict per run.
+
+.DESCRIPTION
+    The V4c blank-world regression was INTERMITTENT: roughly 1 launch in 3 at the
+    worst location, 0 in 7 at the parent commit. A single connected capture is
+    therefore worthless as a gate for this defect class - the broken binary
+    passes it most of the time. This script exists so no future slice can call
+    itself connected-clean on one lucky run.
+
+    Each run: launch connected -> teleloc to the pinned worst-case cell ->
+    wait for world-visible -> settle -> screenshot -> graceful close -> cooldown.
+    The verdict is by screenshot content size: a rendered 1280x720 world compresses
+    to ~1.5 MB; the blank-world failure produces a few-KB flat PNG. The teleloc is
+    pinned because the failure rate is location-sensitive, and stray input into a
+    minimized window silently moves the character between runs.
+
+    Graceful close matters: a hard kill leaves ACE holding the session ~3 minutes
+    and every subsequent run fails with 'CharacterList not received'.
+
+.PARAMETER Runs
+    Cycles to run. Default 10. The defect's observed rate was ~1/3, so ten clean
+    runs bound it below ~4% at 90% confidence - adequate for a re-land gate.
+
+.PARAMETER ExePath
+    Client executable. Defaults to this repo's Release output.
+
+.PARAMETER Teleloc
+    The pinned location, as the full /teleloc argument string. Default is the
+    cell with the worst observed failure rate (5/5 blank at the V4c HEAD).
+
+.PARAMETER MinRenderedBytes
+    Screenshot size below which a run is called blank. Default 500000.
