Webhook callback support for generation completion and PDF API notifications

Webhook callback for generation completion? Webhook callback for generation completion? Building an app that triggers PDF generations via your API. Serverless functions timeout (150s) before generations complete (1-5 min), forcing me to maintain separate polling infrastructure. Would love a simple callback option:

POST /generations { ..., callback_url: "https://..." }

On the roadmap? Happy to beta test.
