Adds RuntimeOptions.RetailUiImporter (ACDREAM_RETAIL_UI_IMPORTER=1) — a new
opt-in flag that runs the LayoutImporter-built vitals window ALONGSIDE the
hand-authored vitals panel for pixel-for-pixel A/B comparison. The importer
window is placed at x=200, y=30 so both render simultaneously within the same
ACDREAM_RETAIL_UI=1 session. The hand-authored path is entirely untouched and
remains the default; the importer path is the eventual switch-over target.
Also adds two RuntimeOptionsRetailUiTests covering the new flag: value "1" →
true, unset/other → false.

Adds two startup-time env toggles that Phase D.2b's retail-UI panel
frame will read:
- ACDREAM_RETAIL_UI=1 → opts.RetailUi (bool, default false)
- ACDREAM_AC_DIR=<path> → opts.AcDir (string?, default null)
Both follow the existing helper conventions (IsExactlyOne / NullIfEmpty).
No call sites broke because the only construction site in RuntimeOptions.cs
already uses named arguments.
