Function createAssemblyAIWebhookHandler

createAssemblyAIWebhookHandler(
options: CreateAssemblyAIWebhookHandlerOptions,
): (request: Request) => Promise<Response>
Wraps the AssemblyAI webhook scaffolding (auth verification, payload parsing, ack-and-log error handling) so route handlers only supply the domain callback.

Returns a Web-standard (request: Request) => Promise<Response> so it can be assigned directly as a Next.js route handler without pulling next/server into this package.
Parameters
- options: CreateAssemblyAIWebhookHandlerOptions
Returns (request: Request) => Promise<Response>
Example
```
// apps/web/app/api/webhooks/assemblyai/route.ts
  export const POST = createAssemblyAIWebhookHandler({
    onWebhook: async ({ sessionId, body }) => {
      await processAssemblyAIWebhookService({
        sessionId: parseSessionId(sessionId),
        body,
      });
    },
  });
```
