Type Alias CronCallback 

pub type CronCallback = Arc<dyn Fn(CronFire) -> Pin<Box<dyn Future<Output = Result<(), CamelError>> + Send>> + Send + Sync>;

Async, fallible callback invoked on each cron fire.

The CronConsumer builds this from its ConsumerContext to submit an Exchange to the pipeline. Returning Err propagates the failure through CronService::run -> Consumer::start to Route supervision (ADR-0007).
