commands

List all available commands and their argument descriptions. Each entry also carries "category" (e.g. "Playlist", "Media", "Plugins") and "level" (0 Basic / 1 Advanced / 3 Developer) for UI grouping and filtering, plus "disallowMultisync" (true) on a command whose Multisync option should stay hidden - e.g. "If", since multisyncing it would broadcast the raw check to other instances rather than propagate the result of evaluating it.
