Adds a streaming benchmark asserting bounded memory under backpressure and measuring throughput across chunk sizes. Includes memory ceiling validation, NDJSON/gzip framing verification, and documented optimal 512KB chunk size. Key changes: - Added EXPORT_STREAM_CONFIG with 512KB chunk size, 512MB memory ceiling, 10 RPS slow consumer rate - Created comprehensive benchmark test suite in src/tests/performance/exportStream.perf.test.ts - Updated docs/exports.md with performance architecture documentation - Verifies gzip and NDJSON framing remain correct under chunking - Tests slow consumer memory ceiling, large datasets, and abort mid-stream scenarios
