v1.1.0 - WireGuard Egress Backend

Added

• Added WireGuard as a new egress backend alongside v2rayA system-tun.
• Added numeric wizard selections for egress backend and edge mode.
• Added WireGuard config import/paste flow in the wizard.
• WireGuard configs are normalized for gateway use:
  • enforces Table = off
  • keeps IPv4 Address
  • removes DNS lines to avoid changing host DNS behavior
• Added WireGuard activation support via wg-quick@<interface>.
• Added WireGuard health checks:
  • service active
  • interface exists
  • recent handshake
• Added WireGuard diagnostics to tge-logs.

Changed

• tge-ctl --activate no longer starts v2rayA when WireGuard mode is selected.
• tge-apply.path is only enabled for v2rayA system-tun mode.
• tge-apply now supports wg0 or another configured egress interface as TUN_IF.
• GRE health validation now checks local/remote tunnel parameters, tunnel IP, and MTU.
• GRE ensure now recreates a TGE-owned GRE tunnel when it does not match the saved config.

Fixed

• Fixed GRE mode cases where an old gre-egress interface existed but pointed to stale local/remote endpoints.
• Fixed stale tun0 rules when switching from v2rayA system-tun to WireGuard.
• Improved WireGuard paste flow in the wizard by requiring explicit END termination.

Notes

• WireGuard mode is recommended for higher-throughput gateway deployments.
• v2rayA system-tun remains supported.
• TProxy and sing-box TUN are not included in this release.
