Research direction
Start in GithubClient.java at getLatestAzureMcpRelease and follow its call through executeWithRetry. Inspect the GitHub release response and the GithubRelease deserialization path to determine why an object is received where an array is expected; done means Azure MCP Server initialization completes without this exception.
