Streamable HTTP release

This is the first release supporting the new Streamable HTTP transport from protocol version 2025-03-26, which supersedes the SSE transport from protocol version 2024-11-05. 🎉

• See the Streamable HTTP section of the README and the included examples for how to use this new transport in your client or server.
• There's also a guide on backwards compatibility, to maintain support with SSE clients or servers while the ecosystem upgrades to Streamable HTTP.

Please report any issues at https://github.com/modelcontextprotocol/typescript-sdk/issues.
