Summary
Remove interaction readiness forwarding left after the target wait's producer and public contract were retired. Preserve prior warnings and typed replay-cause evidence.
Five files: delete the two forwarding sites and obsolete response/replay/MCP fixtures. Runner and device readiness are unchanged.
Closes #3607.
