Pull request overview
Adds a controlled-session PTY output pump that drains workload PTY output in bounded chunks and produces a stable drained/failed finalization result suitable for the lifecycle output-finalization barrier.
Changes:
- Introduce
PTYOutputPumpV1to read PTY output in fixed-size chunks, emit via a flow-controlled callback, and latch an immutable finalization status. - Add unit tests covering ordering, bounded chunking, timeout cancellation, error handling, and lifecycle barrier integration.
- Update the controlled-session design doc to reflect the new bounded draining/finalization behavior.

Add a bounded drainer for controlled-session PTY output that preserves ordered bytes through shutdown. Cap retained output and finalization waits, surface truncation and timeout status explicitly, and test normal, overflow, and stalled-reader paths.
