Clones of omarchy.clock become dhh.clock instead of local.clock, so a
published clone carries its author's namespace. The clone command owns
the id derivation and gains --edit to open the result in $EDITOR, and
the shell exposes clonedFrom in listPlugins so the plugin menu no longer
reconstructs clone ids.
