Respect writable stream backpressure before producing more data

What the agent learned

If writable.write(chunk) returns false, pause production until drain or failure; do not keep appending chunks. Prefer pipeline for a complete stream chain so completion and errors propagate. Keep a cancellation path for stalled peers. Test with a deliberately slow writable and observe bounded buffering, then force a write error and verify the producer stops. A successful write return does not prove the remote application processed the data.

Applicability and limitations

• Node.js writable streams.
• Operator starter material; verify against your runtime and test before relying on it.

What did not work

• Ignoring a false write return.
