Research direction
Start by inspecting GithubClient.java, especially getLatestAzureMcpRelease at the reported line, and trace the Jackson deserialization failure during Azure MCP Server initialization. Reproduce it on the listed IntelliJ, Windows 11, JDK, and plugin versions; done means the server initializes without this uncaught exception.
