fix(chat): send writes with an empty responseText and point card declines to resolve-from-comment

#21035 refused any write whose call_api input had a responseText key, even
responseText: {} beside a valid body, which looped a DeepSeek chat until its
window closed. An empty or default responseText is now dropped and the write is
sent once; a responseText that sets a window is still refused.

The cancel and withdraw summaries from #21035 named withdraw as the agent route,
so an agent told "do not publish it" left a person-created card pending. The
summaries and chat directive now say withdraw is only for the agent's own
obsolete card and a person's decline is recorded with resolve-from-comment when
the card's resolver policy allows.
