test(vr): gate SortableListFilter·vue (stable sub-pixel text divergence)

The full non-update VR matrix surfaced a stable ~204px (1%) cosmetic difference on the
three unlocked item labels (Drafts/Sent/Archive) — vue is the lone outlier; the other 5
match the shared baseline. It slipped in because Clone/Filter were blessed under --update
without a non-update D-10 verify. It's text kerning/position only (the demo renders +
drags correctly), and NOT the documented macOS text-node split (this is Linux + vue-alone,
while svelte/angular match). Gated pending a call on whether it's the accepted cross-target
text class or a fixable Vue-interpolation/demo difference. Tracked:
.planning/todos/pending/sortablelist-filter-vue-text-divergence.md. (Clone + Showcase pass
D-10 6/6 and stay blessed.)
