Embed Perspective conversation widgets using Google Tag Manager, plus conversion tracking and Sensei fixes

• Embed Perspective conversation widgets using Google Tag Manager without editing your site's code. See the setup guide.
• Count completed conversations as Google Analytics 4 conversions using the embed's built-in events. Set up conversion tracking.

Available in SDK 1.16.0. Hosted perspective.js scripts update automatically; npm users need to upgrade. If you already send custom Perspective events, remove them or turn off the built-in events to avoid counting conversions twice.

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

• Summaries now include the range behind star ratings, and the range and any visible end labels behind number ratings.
• Uploaded files saved as knowledge sources no longer send searches to Perspective's website. Uploaded documents are still not searchable.
• Fixed a case where an AI assistant's unfilled answer link was saved as the participant's reply.

• Deleting a conversation from its page now removes it from the Conversations list without a browser reload.
• Fixed a browser error when a floating embed is removed while its welcome chime is starting.
