Under the hood
The internal-event uploader takes tunable failure, batch-size and timeout limits and reports dropped batches.
The CCR internal-event batch uploader now accepts maxConsecutiveFailures, maxBatchBytes, and requestTimeoutMs overrides, and reports a new tengu_ccr_internal_events_dropped telemetry event when a batch is given up on, distinguishing 'give_up' from '4xx' drop reasons.
