wip(assembler): round S7 -- workers kept busy: in-game cold full view 17.5 s -> 7.8 s

Two admission blockers found by per-frame decline codes: the near reserve held
four slots idle after LOD0 was done (coarse capped at 6), and finished-but-
unapplied results counted against the task cap. Admission now counts queued +
running tasks; near reserve releases once the walkable ring is ready while
stationary (voxel.StreamingDynamicNearReserve, default on). Walkable ring
0.65 -> 0.58 s, full LOD0 2.28 -> 1.44 s, busy workers 2.2 -> 5.6 of 10.
Old behaviour behind voxel.StreamingLegacyPendingResultCap. RMC source reviewed
(read-only): batching/fast-cook ranked, not yet worth it on measured apply cost.

+
+The BuildHost trace counted the old scheduler declines: after LOD0 completed, coarse work
+hit the four-slot near reserve for 877 frames; 806 also had finished results waiting to
+apply and counted against the old cap. The shared dynamic reserve and active-task count cut
+the cold 2,578-key set from 17.527 s to 7.780 s. The walkable ring is 0.581 s and full
+LOD0 is 1.439 s, both inside the requested limits. The full set still misses the roughly
+4.2 s worker-seconds/10-slots estimate, and measured worker task-seconds rose about 10%,
+so this is a throughput win with a tile-cost question left to profile. The moving trace also
+shows a separate `bCoreRegionCompilePending` gate: 10 legacy and 11 dynamic submission passes
+were rejected during region rebuilds despite free slots.
+
+W1/W8/W16 determinism, Core-off, M2 fixtures, SurfaceWorld/FloatingIslands, S3 ground
+agreement and S4 cap coverage passed. Three Standalone captures are saved, but their window
+was hidden/occluded and they do not sign off player-visible enclosure. I reviewed RMC's
+update batching, async collision and render-proxy paths; no change was clearly worth the
+measured apply cost this round. Full commands, hashes, RMC source references, quality
+limits and the async audit are in [WorldAssemblerM3/Round11/REPORT.md](../../WorldAssemblerM3/Round11/REPORT.md).
+
+No new source file was added. The likely compile spots are `VoxelWorld.cpp` and
+`VoxelWorld.h` in the VoxelForge runtime module; the harness controls changed in
+`Tools/TestVoxelForgeCoreWorldHost.ps1`. No owner project/editor, asset or external plugin
+file was modified. No commit, push or stash was made.
