Third Stage D affordance port (302 LoC legacy → action + thin wrapper). The action (`actions/move.ts`) uses the live-drag exception documented in editor/wiki/architecture/tools.md: visual-only updates via `sceneRegistry.nodes.get(id).position` + `useLiveTransforms` during the drag, no scene mutations. Avoids re-rebuilding the fence geometry (many posts + infill panels) every pointer tick. Commit performs the single-undo dance — writes final start/end to scene, geometry rebuilds once, Ctrl-Z reverses the whole drag. Linked-fence cascade follows the same shape as MoveFenceEndpoint — any fence in the same parent that shared an endpoint at activation moves with the drag. `getRegistryAffordanceTool` extracted to `tools/shared/affordance-dispatch.ts` so move-tool.tsx and tool-manager.tsx share the lazy-load helper (no duplicate caches). MoveTool dispatch gains a generic `affordanceTools.move` check after the capability-driven `movable` shortcut — fence routes through here; wall / slab / etc. fall through to their legacy per-kind chain until their D ports land.

/**
|
|
* Phase 5 Stage D — runtime lazy-load of a kind's affordance tool.
|
|
*
|
|
* The editor can't statically import from `@pascal-app/nodes` (the
|
|
* nodes package depends on editor — static imports would cycle). The
|
|
* kind declares its drag-affordance components in
|
|
* `def.affordanceTools[<key>]: () => import('./<name>-tool')`; this
|
|
* helper resolves that to a `React.lazy` component at the call site.
|
|
*
|
|
* Returns null when the kind doesn't declare the affordance — callers
|
|
* mount the legacy fallback in that case.
