A Claude Code or Codex spawn now asks for the structured view unless the
operator says otherwise: the two spawn forms open with the box ticked and
`maestro spawn` takes `--terminal` to opt out. Once the operator works the
toggle, a command change no longer re-ticks it under them.
The support predicate moves to `maestro_protocol::display` so all three
clients gate on the same resolution.
