Add stop button to cancel in-flight requests

Swap the Send button for a Stop button while a response is streaming, letting users abort the current operation cleanly.
Cancelled requests now display "Stopped." instead of an error message.

Also includes two smaller fixes: preserve the original assistant text and full tool_calls array when executing write
tools for follow-up context, and add 'research' to agentic modes.
