Wires the dormant AcDream.App/UI retained-mode tree into GameWindow under ACDREAM_RETAIL_UI=1: an 8-piece dat-sprite UiNineSlicePanel framing three UiMeter vital bars bound to the existing VitalsVM. Render-only (UiHost input not yet bridged to the InputDispatcher — next sub-phase). Coexists with the ImGui devtools path; no regression there. Visually verified against a live retail client: the bars match retail's vitals structure (three stacked horizontal bars, current/max numbers centered) — so the earlier "orbs" assumption was wrong (retail vitals ARE bars), and stamina is GOLD not cyan (the #10F0F0 research note was wrong). UiMeter gains a centered numeric Label (stub debug font for now). Spec §8 + the markup example corrected to match. Bookkeeping: retired divergence row TS-30 (flat-rect panels -> real dat chrome) and added IA-15 (our UiHost/markup engine vs keystone.dll's LayoutDesc tree). Remaining polish (filed, §15): glassy gradient bar fill sprite + the retail dat font for the numbers. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
