 * Exporter for 1st-party event logging to /api/event_logging/batch.
 *
 * Export cycles are controlled by OpenTelemetry's BatchLogRecordProcessor, which
 * triggers export() when either:
 * - Time interval elapses (default: 5 seconds via scheduledDelayMillis)
 * - Batch size is reached (default: 200 events via maxExportBatchSize)
 *
 * This exporter adds resilience on top:
 * - Append-only log for failed events (concurrency-safe)
 * - Quadratic backoff retry for failed events, dropped after maxAttempts
 * - Immediate retry of queued events when any export succeeds (endpoint is healthy)
 * - Chunking large event sets into smaller batches
 * - Auth fallback: retries without auth on 401 errors
