v2.5.0 — System Snapshots, Tailscale VPN & Pre-flight Checks

What's New in v2.5.0

System Snapshot & Restore

• --snapshot captures your entire system state: APT/Snap/Flatpak/pip/npm/Cargo packages, dotfiles, cron jobs, GNOME settings, VS Code extensions, browser profiles, SSH/GPG key metadata, and more
• --restore-snapshot generates a phased bash/PowerShell restore script to rebuild your machine after a format
• --snapshot-diff compares two snapshots to track what changed over time
• Supports both Ubuntu/Linux and Windows

Tailscale VPN Integration

• Automatic Tailscale VPN connection with pre-auth keys for secure SSH backups over private tailnets
• CLI flags: --tailscale, --tailscale-authkey
• Config section [TAILSCALE] with hostname, ACL tags, accept routes, and auto-disconnect options

Pre-flight Mount Checks

• Backup destinations under /mnt/ are verified as mounted before starting
• If the disk is unmounted, backup aborts early with clear error + Telegram notification
• Applied to both CLI and scheduled modes — no more silent failures

Other

• Cron log moved to local path to prevent log failures when backup disk is unmounted
• MIT License added
