[SamNet-dev]

🚀 v1.0.2: Docker-Safe Firewall & TUI Port Management

This release brings firewall management, seamless Docker compatibility, and smarter cleanup.

🔥 Firewall System

• New Firewall Ports TUI: Manage open ports directly from the terminal (Security → Firewall Ports).
  • Supports TCP, UDP, or Both.
  • Protected mode: Prevents accidental VPN/SSH lockouts.
  • [V] View Rules: Instantly see current active firewall rules regardless of managed mode (SamNet or External).
• Smart Service Detection: Installing on a server with existing apps? SamNet now auto-detects running services (Nginx, Postgres, Prometheus, etc.) and whitelists them automatically.
• Zero-Touch Logic:
  • Detects UFW/iptables? Defaults to external mode (safe).
  • Clean system? Defaults to SamNet mode (managed).

🐳 Docker Compatibility

• Non-Interfering Rules: Firewall rules now run at priority 10 (after Docker), ensuring container networking works out of the box.
• Bridge Support: Explicitly allows traffic from docker0 and br-* interfaces.
• Clean Uninstalls: Removal process explicitly cleans up iptables forwarding rules added for Docker support.

🛠️ Tooling & Cleanup Updates

• Surgical Uninstall: The uninstaller now detects and removes samnet-nat6 tables and samnet-wg-sync services.
• Safe Port Removal: Uninstaller asks before deleting your custom samnet-ports rules.
• Advanced Tools Updates:
  • Firewall Diff: Now shows your managed ports file samnet-ports.nft.
  • Troubleshooter: Automatically diagnoses missing firewall tables.

📦 Installation

• Faster pre-flight checks (1s timeout).
• Parallel IP detection.
• Full IPv6 support in all rules.
