[Bug] SSH authentication fails when installing plugins from private GitHub marketplace on Windows Claude Code CLI

Bug Description
Issue installing a Claude plugin from a private marketplace on a github repo that uses SSH authentication, on the Windows Claude CLI.
Repro: 1. authenticate via SSH with the github desktop client. 2. ssh -T git@github.com should work. 3. Attempt to install plugin from private github claude marketplace. 4. You'll get errors about the key being invalid. Current workaround is to resort to HTTPS auth, and use git config --global url."https://github.com/".insteadOf git@github.com: to transform the SSH URLs in the marketplace into HTTPS URLs.
