fix: detach stdin on remaining git subprocess calls

Apply the same stdin=DEVNULL treatment to the git clone/config/checkout
calls in cloning.py and github_processor.py so no git child process
inherits the parent's stdin (the MCP JSON-RPC pipe when run as a server,
or an interactive terminal where git could otherwise block on a prompt).
