v0.2.7

v0.2.7

✨ Features

• Added human-in-the-loop tool approval hook tool_approval_handler on Conversation,
  enabling manual review/approval of each tool call before execution.
• Implemented a minimal WebSocket-based browser demo
  (examples/tool_approval_web_demo.py) that shows how to:
  • Send user messages from a web page
  • Receive tool approval requests from the server
  • Let users approve/deny tool calls in the browser, and feed the decision back
• Improved the tool rejection behavior so that, when a tool call is denied,
  the model receives a strong natural-language signal to stop using tools and
  answer directly, reducing repeated tool-call loops.
