Subject: [PATCH] fix(fixture): follow the message-event shape and keep
 todo_write the alpha log tail

The multimodal sample turn carried the pre-send-unify event shape (bare
content/provenance instead of the message wrapper), crashing the built
client fold; it also sat after the todo_write turn, retiring the plan
projection the TodoPanel tests pin. Wrap both messages through the
fixture helpers and order the image turn before the todo turn; re-record
the code-mode trajectory ordinals the two added message nodes shift.
