Agent workspace renders tool results as live charts instead of plain text

A developer's agent workspace upgrades the chat UI pattern: when tools return structured numeric data, the frontend renders an actual chart component instead of a text paragraph, shows tool calls running live, and cites the data source inline. Under the hood it's a LangGraph ReAct agent over a custom MCP tool registry, so new tools plug in without frontend changes. Repo and demo in comments.
