/**
 * eeschema Yjs collaborative bridge (features/yjs-bridge commit 3).
 *
 * eeschema reuses the same wire contract + generic JS reconciler as pl_editor; the new
 * code is the C++ adapter — native SCHEMATIC_LISTENER emit + SCH_COMMIT apply, the latter
 * run inside a COROUTINE so SCH_ITEM::Move has the Asyncify/fiber (tool-coroutine) context
 * it requires. Coverage:
 *   - snapshot (read): kicadCollabSnapshot reflects items by uuid/type/position.
 *   - apply (single page): kicadCollabApply moves/removes by uuid (deferred via CallAfter
 *     + coroutine, so poll for the result).
 *   - two-tab: a real local move propagates A→B over BroadcastChannel.
