What's Changed

feat(cascade): add mKCP (UDP) transport for cascade links (#132)

Added mKCP UDP transport for inter-node cascade tunnels (both Reverse and Forward modes) to mitigate peak-hour TCP throttling, packet loss, and DPI degradation on transit links.

  • Client Inbound Unaffected: Clients continue connecting via standard TCP inbounds (REALITY / VLESS), while traffic between nodes is forwarded through mKCP over UDP.
  • Security & Obfuscation:
    • Automatically generates a 128-bit key on the server (kcpPassword).
    • Utilizes modern finalmask.udp with mkcp-legacy AEAD stream encryption and optional header camouflage (wechat, dtls, srtp, wireguard).
  • Performance Settings: Configurable MTU (576–1460), TTI (10–100 ms), and uplink/downlink capacities (1–1000 MB/s, default 100 MB/s).
  • Core Compatibility & Safety Guards:
    • Requires Xray core >= 26.6.1 for mKCP links; nodes with older cores safely skip incompatible cascade links without breaking sync or config generation.
    • Automatic detection of UDP port collisions with co-located Hysteria 2 nodes and port-hopping ranges.
    • Conntrack-aware UDP health probes for accurate tunnel status detection.
