feat: connect to MCP servers that speak protocol version 2026-07-28 (#33087)
Upgrade the MCP SDK to 2.3.0 and build MCPClient on its Client in
mode='auto', which probes server/discover for the stateless 2026-07-28
protocol and falls back to the initialize handshake for legacy servers.
MCPClient's public surface is unchanged.

MCP_INITIALIZE_TIMEOUT becomes the session's default request timeout, so
it bounds the legacy handshake, tool listing and resource reads; tool
calls keep using AIOHTTP_CLIENT_TIMEOUT_TOOL_SERVER.

Relates to #29778
