Chat Experience Upgraded

#Full chat UX in tasks

Full chat UX in a task, with a rich text composer, mentions, and a resizable diff panel

Task pages now include a full chat experience so you can follow up with the agent right where work is happening. The new composer supports rich text, mentions, and keyboard shortcuts (including Cmd/Ctrl + Enter to send), plus quick actions like connecting repos, changing agent/branch, retrying, stopping, and generating a PR.

Messages you send while the agent is working are queued and sent in order. If you're reviewing changes, you can also resize the diff panel to give more space to the chat or the code.

#Sonnet 4.6 model support

Sonnet 4.6 is now available as a model option in both Claude Code and OpenCode.

Various bug fixes and improvements :)
