Sensei fixes for Live endings, crawler conversations, and summaries, plus embeds without hidden search markup

Sensei, our AI conversation quality coach, found these problems by reviewing completed conversations and production signals.

• Fixed a case where Live browser calls ended after a brief acknowledgment, cutting off the closing message.
• Participants who block their microphone and continue in text can now allow it and press "Try again" to return to a voice call they can see and control.
• Visits from Meta's and other indexing crawlers no longer open conversations on your agents, so they stop showing up as abandoned conversations and no longer use credits.
• Conversation summaries now include questions asked as quick replies, so a valid answer is no longer marked as unconfirmed.

JavaScript and React embeds using SDK 1.15.3 no longer add a hidden Perspective product listing to your website's search-engine markup. Hosted perspective.js scripts update automatically; npm users need to upgrade to 1.15.3.
