🔧 Review for OB-1885: VPS Beam Validator Setup

Thank you for automating the AvalancheGo + Beam Subnet-EVM install! This PR greatly simplifies spinning up a validator. A few quick observations:

✅ What’s Working Well

• Interactive prompts guide users through connection type, IP selection, RPC exposure and state-sync choices.
• Modular scripts (1-install_avalanchego.sh & 2-install_beam_network.sh) keep concerns separate and easy to maintain.
• Verbose logging and post-install instructions (NodeID extraction, systemd status, log tailing) make it clear what to do next.

💡 Suggestions

• Root check & dependencies: Early bail if not run as sudo/root, and verify required binaries (wget, jq, tar) before proceeding.
• Non-interactive mode: Consider adding --yes or --quiet flags for CI/CD or headless installs.

Thank you for this comprehensive ops-automation pass! Automating AvalancheGo + Beam Subnet-EVM installation will make validator spin-ups a breeze.

✅ What’s Working Well

• Interactive Prompts guide users through connection type, IP selection, RPC exposure and state-sync options.
• Modular Scripts (1-install_avalanchego.sh & 2-install_beam_network.sh) keep each concern isolated and maintainable.
• Verbose Logging & Post-Install Guidance clearly surface NodeID extraction, service status checks, and log-tailing commands.

💡 Improvement Suggestions

1. Root Check & Dependencies
   At script start, bail early if not sudo/root and verify required tools (wget, jq, tar) are installed.
2. Non-Interactive Flags
   Add --yes/--quiet options for headless or CI-driven installs.
3. Config Backup
   Before mutating node.json, create node.json.bak so users can roll back if needed.
4. Version Pinning & Dynamic Upgrades
   Surface AvalancheGo & Subnet-EVM versions in variables (or fetch via GitHub API) to avoid stale downloads.
5. Shebang & Executability
   Use #!/usr/bin/env bash for portability and ensure both scripts are chmod +x in the repo.

📝 Minor Nits

• Standardize quoting style around variables (e.g. "$NODE_CONFIG").
• Normalize log-grep patterns to avoid whitespace mismatches.
• Inline comments in check-deploy.sh could mention expected exit codes for CI clarity.

Overall, this is a solid ops-hygiene contribution. Once the above tweaks are in, I’m happy to ✅ approve and merge. Let’s empower validators everywhere! 🚀
