Adds `_server_info` attribute to ClientSession that is populated from InitializeResult.server_info after initialize() completes. Also adds a `get_server_info()` accessor method matching get_server_capabilities(). This lets clients access the server's name and version without needing to capture the initialize() return value. Fixes modelcontextprotocol#1018 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
