Subject: [PATCH 1/2] test(quick-start): cover browser autocomplete contract

Protect the conversational input contract from regressions.

Subject: [PATCH 2/2] fix(quick-start): disable prompt autocomplete

Saved form entries appear over the conversational creation composer.

Disable autocomplete on both the prompt field and its form.

Keep browser history suggestions out without changing generation behavior.
