Research direction
Start in GithubClient.java at getLatestAzureMcpRelease, especially line 103, and trace the call through executeWithRetry. Inspect the GitHub response shape that triggers the MismatchedInputException and identify the expected handling; done means Azure MCP initialization no longer raises this uncaught deserialization error.
