Changelog: Migrated the ingestion service from polling to webhook-based event delivery. P95 latency for downstream sync dropped from 95s to 4s. Deprecated the /v1/poll endpoint; clients must move to /v2/events by August 31. Added exponential backoff with jitter to the retry path, which removes the duplicate-delivery edge case reported in incident INC-2214.
