Research direction

Start in GithubClient.java at getLatestAzureMcpRelease, line 103, and reproduce Azure MCP Server initialization on the reported IntelliJ, Windows 11, and JDK versions. Trace the empty response that causes Jackson's MismatchedInputException; done means initialization completes without an uncaught exception.
