TK-00134: fix documented cleanWallpaper snippet in CLAUDE.md to brand-aware

The canonical helper that gets copy-pasted into every updater was still the blanket
version in the docs — the source of the fleet-wide brand-name corruption. Replaced
with the brand-aware + derived-word-safe version (matches the 13 code copies), plus a
warning explaining the 17-brand hazard. Verified the doc snippet is copy-paste-correct.

 **Post-processing cleanup (MANDATORY in all updaters):**
+⚠️ MUST be **brand-aware** — 17 legitimate brand names END in "Wallpaper" (Ralph Lauren,
+Missoni, Grasscloth, Scalamandre, Schumacher, etc.) and a blanket `\bWallpaper\b` swap
+CORRUPTS them (e.g. "Ralph Lauren Wallpaper" → "Ralph Lauren Wallcovering"). It must also
+skip the derived words `wallpapered`/`wallpapering`. Use this version (TK-00134):
 ```javascript

   if (!str) return str;

-    .replace(/\bWallpaper\b/gi, 'Wallcovering')
-    .replace(/\bWalls Wallpaper\b/gi, 'Wallcoverings')
-    .replace(/\bWallpapers\b/gi, 'Wallcoverings');
+  // Preserve the 17 brands ending in "Wallpaper"; skip wallpapered/wallpapering; case-preserving.
+  const WALLPAPER_BRANDS = ['Apartment','Boråstapeter','China Seas','DW Exclusive','Edge','Fentucci','Grasscloth','Laura Ashley','Malibu','MC Escher','Missoni','Nicolette Mayer','PS Removable','Ralph Lauren','Roberto Cavalli','Scalamandre','Schumacher'];
