* fix(ci): update MCP SDK version check from 1.20.1 to 1.27.1

The dependency-check workflow was hardcoded to expect MCP SDK 1.20.1,
causing CI failure after the intentional upgrade to 1.27.1.

* fix(tests): close existing connection before reconnecting in MCP protocol tests

MCP SDK 1.27+ enforces single-connection per Server instance, throwing
"Already connected to a transport" when connect() is called twice.
Updated test helper to close existing connections before reconnecting.
