Wassim SAMADandClaude Opus 4.7 c3e255b58a wiki(tools): clarify useLiveTransforms.position semantics for polygon kinds
Two regressions in the Stage D port surfaced the same gap: the wiki
already said "the mesh offset must mirror the useLiveTransforms entry"
but didn't spell out that for polygon-based kinds (slab / fence /
ceiling / wall), the value to mirror is the DELTA (the group's local
position) — not the world location of the polygon's center.

Expanded the live-drag rule with a position-based vs polygon-based
split and an explicit note that ParametricNodeRenderer reconciles the
group's position via React on every Zustand notification, so the two
writes must agree to the exact value or they fight every frame.
