Query a call run by run_id.

First, use this to plan the call. If 'ready_to_run' is false, ask for missing details and call this again with 'user_input' set to the user's response. Once 'ready_to_run' is true, proceed to 'run_call' with the 'confirm_token'. Do not guess parameters.

PUBLIC WRITE Open world Executes the planned call. Use only after 'plan_call' returns 'ready_to_run=true'. Pass the 'confirm_token' exactly as received. If the call starts, it runs asynchronously. Do not perform extra operations; the server will notify on completion. Do not call 'run_call' more than once for the same 'plan_id'. Once started, wait for the activity card updates.
