build_resume_command

Build a resume :class:Command from the request's input items.

Default implementation scans the current request for either a function_call_output whose call_id matches one of the pending interrupts, or an mcp_approval_response whose approval_request_id matches. The former decodes its output JSON into a :class:Command; the latter maps recognized LangChain HumanInTheLoopMiddleware requests to ordered approve/reject decisions. Other approvals echo the interrupt's value. Override to plug in custom resume protocols.
