fix: add /root/.ggo directory cleanup in uninstall script

The uninstall script was missing cleanup for /root/.ggo directory.
It was only cleaning up /root/.config/ggo and /root/.gpugo, but
the agent can also create /root/.ggo directory which needs to be
removed during uninstallation.

Changes:
- Added /root/.ggo directory cleanup in remove_config()
- Updated conditional check to include /root/.ggo
- Added /root/.ggo to manual cleanup warning message
