fix: resolve conflicts between modules and improve reliability

- Remove duplicate SSH_AUTH_SOCK configuration in apps.sh (now handled by gcr-ssh-agent)
- Remove duplicate system update in apps.sh (now only in install_all)
- Remove duplicate packages from zsh-config (git, zoxide, fastfetch, yt-dlp)
- Add mg_dotfiles verification warning for Zsh/Hyprland modules
- Make .zshrc backup non-critical to avoid interruption
- Improve service verification with status checks before enabling
- Add clarifying comments about cursor configuration layers
