Erik bf77a23ad3 feat(D.2b): flip vitals to the LayoutDesc importer; retire hand-authored vitals.xml
The importer (proven pixel-identical at the 2026-06-15 A/B gate) is now the
default vitals window when ACDREAM_RETAIL_UI=1 — data-driven from LayoutDesc
0x2100006C. Removed: the hand-authored vitals.xml build path, the asset file
(recoverable from git history), and the now-obsolete ACDREAM_RETAIL_UI_IMPORTER
flag (RuntimeOptions param + parse + 2 tests). The window is user-positioned at
(10,30) and movable; resize stays off — the dat stacked-vitals layout is fixed-
size (chrome edges near-pinned), faithful grip/dragbar resize is Plan 2.
MarkupDocument/UiNineSlicePanel remain for the chat window + plugin panels.

AcDream.App builds 0/0; AcDream.App.Tests 352 passed / 1 skipped / 0 failed.
