Research direction

Start with the stack trace location in GithubClient.java:103 and trace the surrounding executeWithRetry flow at GithubClient.java:64. Reproduce the Azure MCP Server initialization on the reported IntelliJ, Windows 11, JDK 21, and plugin versions, then verify that initialization no longer raises the reported Jackson deserialization exception.
