A suggestion card sends its prompt

Filling the composer and waiting for Enter made the card a form to review
rather than a thing to press. One click, one reply.

That changes what a prompt has to be. The built-ins ended mid-sentence --
"My plan: " -- because nothing was sent until the person finished the
thought; sent cold they are a model guessing at material nobody gave it. All
three are rewritten to ask for what they need, so the first reply is the
right question instead. There is a test that they end as complete sentences,
since the failure is silent and only visible in the answer.

requestSubmit, not submit: it fires the submit event, which is what htmx
listens for. Same call the Enter key already makes.

Version bumped because app.js is what changed, and the service worker caches
it -- without the bump the first load after this would still only fill the
box.
