Raw-text forwarding over the subagent bridge is a separate switch, off in this build.

What

A new helper decides what a subagent bridge passes along. Forwarding of frames is on by default; forwarding of raw text is a separate switch that is off in this build.

Details
  • The two settings are independent, so text forwarding stays off even with frames enabled.
