The no-world card asks for a title, a name and an optional brief and offers
one Begin button. world.begin takes the world_create.v4 payload (the fields
the form no longer asks for ride the button's action as authored constants)
and submits create, approve and activate as three separate kernel commands,
stopping at the first refusal. The create path is shared with world.create.
Step ids are derived from the Begin's key so a replayed Begin replays through
the kernel's ledger. A refusal never echoes a typed value, including the
jurisdiction-handle refusal on world.create.
Not yet built or run: the bridge fixture still carries the old
create/approve/activate steps (re-derived from the real client in a later
commit), and the ignored bridge tests have not run.
