Research direction

Start at GithubClient.java:103 and trace the call through executeWithRetry at line 64, using the reported IntelliJ, plugin, and JDK versions to investigate the Azure MCP initialization failure. Determine the expected GitHub release response and verify that server initialization no longer produces the reported uncaught deserialization exception.
