* fix(web): stop Nexus AI agent when user clicks Stop
Wire AbortController through chat streaming so Stop cancels the LangGraph
run instead of only hiding the loading UI. Fixes#1615.
* fix(web): address PR review feedback for Nexus AI stop
Guard stream cleanup against Stop-then-Send races, remove dead cancelled
handler, tighten abort error detection, add stopped tool-call status, and
extend abort unit tests. Fixes#1615.
