  1. Update HttpClientSseClientTransport.java 

    fix: switch HttpClient to HTTP/1.1 to prevent body loss with Python servers

This change modifies the HttpClient configuration to explicitly use HTTP_1_1 instead 
of the default HTTP_2, resolving a critical compatibility issue with Python-based 
servers (uvicorn/starlette) that cannot properly handle HTTP/2 upgrade requests with 
bodies.

The issue occurs because:
1. Java's HttpClient attempts to upgrade to HTTP/2 (h2c) while simultaneously 
   sending request bodies
2. Python servers (particularly with HttpToolsProtocol) prioritize protocol upgrade 
   handling, causing the body parsing to be skipped or interrupted
3. This results in request bodies being lost during transmission
