/**
 * Core registry module.

 * Purpose: Maintains a registry mapping editorId → editor context.

 * Key responsibilities:
 * - Register editor instances with their configuration
 * - Retrieve editor contexts by ID
 * - Unregister editors when they're destroyed
 * - Extract editor IDs from editor instances
 *
 * Dependencies: types/common.ts, core/state.ts, adapters/host/doc.ts
