Start by reading the stack trace locations in GithubClient.java, especially lines 64, 118, and 123, then follow how AzureMcpPackageManager initializes the server. Reproduce initialization with IntelliJ 2026.1.3 on Windows 11 and inspect the download retry path. Done means the reported initialization exception is handled or no longer occurs in the affected setup.
