/**
 * Registry-driven item placement tool. Mounted by `ToolManager` when
 * `useEditor.tool === 'item'` (the catalog picker is what selects which
 * asset; this tool handles the cursor follow + click-to-commit flow).
 *
 * Wraps the same `usePlacementCoordinator` + `useDraftNode` primitives
 * the move-tool uses. The placement coordinator runs surface strategies
 * (floor / wall / ceiling / item-surface) so the same cursor logic
 * handles wall-mounted artwork, floor furniture, ceiling fans, and
 * nested items on tables.
 *
 * Replaces the legacy `editor/src/components/tools/item/item-tool.tsx`.
 * The `tools` map in `tool-manager.tsx` no longer needs an `item:` entry
 * — `getRegistryTool('item')` finds this through `def.tool`.
