Research direction
Start with GithubClient.java at getLatestAzureMcpRelease (line 103) and follow executeWithRetry at line 64. Inspect the release response and the deserialization path to reproduce the initialization failure; done means the Azure MCP Server initializes without this uncaught exception.
