…ws CRLF corruption On Windows, TextIOWrapper defaults to platform-native line endings (\r\n), which corrupts newline-delimited JSON-RPC messages over stdio. Add newline='' to both the stdin and stdout TextIOWrapper constructors in stdio_server(), matching the pattern from PR modelcontextprotocol#2302. Fixes modelcontextprotocol#2433
