Research direction

The stack trace points to GithubClient.java:103, reached through executeWithRetry at GithubClient.java:64; start there and inspect the latest Azure MCP release lookup. Reproduce the deserialization failure with the reported IntelliJ and Windows setup, then verify that the lookup completes without the uncaught exception.
