feat(command): surface one-shot commands in command-line autocomplete

File/view/layer/style/undo-redo and similar one-shot commands dispatch a
single action instead of installing an interactive CadCommand, so they had no
module to register from and never appeared in autocomplete. Add a consolidated
CommandRegistration covering all 132 user-typeable one-shots (NEW, OPEN, SAVE,
SAVEAS, PLOT, PURGE, UNDO, REDO, ZOOM, LAYER, XREF, …). Internal dispatch
tokens the user never types (REFEDIT_BEGIN, REFCLOSE_SAVE, REFCLOSE_DISCARD)
stay excluded.
