Add parallel event ingestion to Tinybird alongside existing Postgres/ClickHouse flow.
Events are sent to both systems simultaneously via EventBatchingManager.
- Add Tinybird client setup and ingest endpoint (zod-bird)
- Add event mapping and send utilities with retry/error handling
- Add complete Tinybird datafiles (datasources, pipes, materializations, copies, scripts)
- Modify EventBatchingManager to dual-write to SQS + Tinybird
- Route track events through batching manager
Tinybird will silently skip if not configured (TINYBIRD_URL/TINYBIRD_TOKEN).
