/**
 * Dynamic ESM import helper.
 *
 * TypeScript compiles `await import('x')` to `require('x')` when the target
 * module format is CommonJS. This breaks ESM-only packages like `chat` and
 * `@chat-adapter/*` which only export via `"import"` in their package.json.
 *
 * This helper uses `new Function()` to create an `import()` call that
 * TypeScript cannot see or transform, preserving the native ESM import.
 *
 * The `typeof import(...)` type annotations below are necessary to get type
 * safety for the dynamically-loaded modules and are not convertible to
 * `import type` syntax.
