fix: remove redundant sudo commands from setup.sh

- Removed sudo from Node.js installation commands (curl ... | bash -)
- Script already runs as root (check_root enforced at start)
- Redundant sudo commands are unnecessary when script has root privileges
- Applied to both apt-get and yum package managers

scripts/setup.sh
