Smoother conversations and more precise GIF editing

Conversations with attachments now finish more reliably.

Editing a GIF better preserves your requested frame count.

Clearer error codes make it easier to report a problem and get help.

Clearing Feishu Bot conversations is now more reliable.

After a disconnection, conversations no longer get stuck processing with endless retries.

Stop a reply immediately and pay only for the content already generated; your reply stays available after stopping and refreshing.

Ask a follow-up during a reply and receive a separate answer in the right order.

Model timeouts now show the actual reason, and brief network drops are less likely to interrupt a conversation.
