Extends TestRetryDelivery to verify that the manual retry API publishes a DeliveryTask with complete event data to deliveryMQ. This ensures the deliverymq handler receives full event data for manual retries, consistent with the scheduled retry flow which fetches event data in the retry scheduler.

Add unit and e2e tests verifying that retries are not lost when the retry scheduler queries logstore before the event has been persisted. Test scenario: 1. Initial delivery fails, retry is scheduled 2. Retry scheduler queries logstore for event data 3. Event is not yet persisted (logmq batching delay) 4. Retry should remain in queue and be reprocessed later Tests added: - TestRetryScheduler_RaceCondition_EventNotYetPersisted (unit test) - TestE2E_Regression_RetryRaceCondition (e2e test) Also adds: - RetryVisibilityTimeoutSeconds config option - WithRetryVisibilityTimeout scheduler option - mockDelayedEventGetter for simulating delayed persistence Co-Authored-By: Claude Opus 4.5 <[email protected]>
Return error instead of nil so the retry message stays in queue and will be reprocessed after the visibility timeout. Co-Authored-By: Claude Opus 4.5 <[email protected]>

Moves event fetching from the delivery flow to the retry flow.
What changed
Why this design
Scheduled retry tasks only store event IDs (not full payloads) to keep queue messages small. Previously, the delivery handler had to detect retries via
event.Time.IsZero()and conditionally fetch event data.Moving this to the retry scheduler is cleaner because:
Both entry points now consistently provide full event data to the delivery queue:
