fix: soft-detect submission + only NEW completion messages count

- countDoneMsgs baseline before submit: lingering 'has been scheduled' chatter from
  the PREVIOUS gen no longer triggers an instant post-gen reload (the self-reload bug)
- promptEchoed: chat echoing the prompt = strongest it-stuck signal, added to the
  post-Enter check; and on retry it means the earlier submit registered -> skip
  re-typing entirely (no double generation / double credits)
