Code Review
This pull request formalizes the A2UI-over-MCP transport binding and aligns the sample server implementation. The documentation additions in a2ui_protocol.md for both v0.9 and v0.10 are clear, detailed, and well-structured. The corresponding changes in the Python sample server correctly reflect the spec by using a messages key and introducing a constant for it, which improves code quality. My only feedback is a minor suggestion to improve link consistency in the markdown files.
