Runs a periodic task until shutdown.

The first iteration runs immediately unless the token is already cancelled. Each later iteration sleeps using the latest product-provided interval and optional jitter cap. Panics in one iteration are converted into a product outcome through panic_outcome and then recorded by record_outcome; they do not kill the worker loop.
