Global coordinator for hierarchical keyboard system management with single-listener event dispatch.
Coordinator Setup
The coordinator is a global singleton (window.kbCoordinator) that manages registration, hierarchy, and event dispatch for all keyboard systems on a page. Each keyboard system registers its handler instead of adding its own document.keydown listener. The coordinator owns the single listener and routes events through the parent-child hierarchy: deepest active child handles first, unhandled events bubble up.
