## Title

    Proposed fix: [Braintrust SDK] Logs lost: "log request failed after N retries. Dropping batch" (background logger)

## Body

    Recommended action: Set BRAINTRUST_FAILED_PUBLISH_PAYLOADS_DIR to keep failed payloads, enable debug logging (BRAINTRUST_DEBUG_LOG_LEVEL), tune BRAINTRUST_NUM_RETRIES / BRAINTRUST_MAX_REQUEST_SIZE, and always await flush() before process exit in serverless.
