Code Review

This pull request updates the Model Context Protocol documentation to add StreamableHTTP as a transport option. The changes are a good addition, but I have one suggestion to fix a missing heading in the markdown. I also noticed that the MCPClientOptions struct definition was not updated to include the new StreamableHTTP field, which makes the documentation inconsistent. Since this is outside the changed lines, I couldn't add a specific comment, but it would be beneficial to include this update.
