Same prompt, other clients

Read from the server itself, by connecting to it and calling prompts/list on 16 October 2026. A listing does not declare its prompts, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each prompt's arguments.
