/**
 * The portable kernel: the contracts every model call and tool call is built on, for any JavaScript
 * runtime. That means Node.js, Deno, Bun, edge runtimes such as Cloudflare Workers and Vercel's,
 * and browsers.
 *
 * Nothing here, nor anything it imports, uses `fs`, `net`, `child_process`, Node's `crypto`, or
 * Node's globals, and CI runs its tests on each runtime. The provider adapters, graphs, agents, and
 * protocols are portable too, on their own entry points.
