summary

Envoy external processing filter no longer requires 1x1 body streaming and now supports MxN/full duplex stream so a side‑stream can buffer M incoming chunks, process them (example: compression), and emit N response chunks. Implementation adds an API flag to tell Envoy more response chunks are coming, state‑machine actions to forward chunks immediately while awaiting header replies, and a config knob for security. Feature is implemented in the filter and supports both downstream→backend and backend→client flows.
