// ==========================================
// Chat Switchboard — SDK Entry Point
// ==========================================
// Assembles all SDK modules into the `sw` object
// and runs the boot sequence.

// Usage:
//   import { boot } from './js/sw/sdk/index.js';
//   const sw = await boot();
//
// Exports: boot() → window.sw
