🔄 Reset Node - Clean reinstall of Demos Network node

USAGE:
    ./reset-node [OPTIONS]

OPTIONS:
    -y, --yes       Skip confirmation prompt
    -h, --help      Show this help message

DESCRIPTION:
    This script performs a complete clean reinstall of the node software
    while preserving your identity and peer list files.

    Files preserved:
    - .demos_identity (your node identity - IMPORTANT!)
    - demos_peerlist.json (your peer connections)

    What happens:
    1. Backs up identity and peerlist to parent directory
    2. Removes the entire node directory
    3. Clones fresh copy from GitHub
    4. Restores identity and peerlist
    5. Runs bun install

WARNING:
    This will delete ALL local changes, logs, and data!
    Make sure you have backed up anything important.
