amal66 makes chat titles stop crashing short conversations

amal66 has tightened the plumbing behind both ordinary chat and project-based chat. The issue appeared when a conversation ended before its AI-generated title was ready: the title update could try to reach a stream already closed, causing an uncaught error even though the underlying request had succeeded.

The fork now safely ignores that late client update while retaining the title for the next page load. It also removes live AI-provider calls from relevant automated checks and makes any accidental network request fail immediately. That should mean faster, more repeatable release checks instead of outcomes shaped by provider latency or retries.
