docs(render): correct V6i-2's pixel-gate figures to commit order

The three measurements were recorded out of order. Commit 1 measured 3.02e-05
(17 px), commit 2 measured 3.20e-05 (18 px) and commit 3 measured 1.60e-05
(9 px) — not the ascending sequence §5.5.13 listed. The band and the verdicts are
unchanged; what was wrong is which commit each number belongs to, which is
exactly what the figures exist to say.

Also records the suite totals in the V6i row.

 | **V6h** ✅ | **The Vulkan composition host**, specified by §5.5.9 and reported in §5.5.10. `ACDREAM_RENDER_BACKEND=vulkan` runs the real `GameWindow` composition — DAT load, streaming, camera, entity table, session, and the real retained `UiHost` through the RHI — with no world renderers. Three seams: the already-generic platform acquisition now publishes a `GameWindowGraphics`; `VulkanHostInputCameraCompositionFactory` is the host-phase fork; the frame root gains a Vulkan arm. `VulkanBringUpHost` is reduced to the capability-probe harness over the extracted `VulkanGraphicsContext`. | offline Vulkan launch reaching the real composition with the client's own UI captured, one validation-layer run at 0 errors / 0 warnings, converging ownership ledger, App tests 4,075/3, complete Release suite 9,138/5, GL offline pixel gate 1.78e-05 |
