VPS checkup (Ubuntu + Docker)

Goal

• Produce a clear, read-only health/security/update report for an Ubuntu VPS running Docker.
• Propose safe, minimal fixes; do not apply changes or restart anything unless the user explicitly confirms.

Inputs to ask for (if missing)

• SSH target host alias (from ~/.ssh/config on Windows: $HOME\\.ssh\\config) or user@ip.
• Confirm sudo access and whether running apt update is allowed (it modifies package lists).
• Required open ports (e.g., 22, 80, 443) and any non-standard SSH port.
• Where deployments live: confirm if Docker Compose is used on the VPS (common), and whether compose files are in a known path.
• If the local ssh client or required tools are missing, tell the user and ask whether to install them or provide command output manually.
