VLESS protocol: Add lightweight, Post-Quantum ML-KEM-768-based PFS 1-RTT / anti-replay 0-RTT AEAD Encryption https://github.com/XTLS/Xray-core/pull/5067

Xray-core v25.9.5 未来已来，本次重点更新内容：

过于先进的 VLESS Post-Quantum Encryption： - 抗量子的密钥交换与身份认证、前向安全、客户端配置安全、0-RTT - 无需对时、完美的重放防护、无需多次尝试解密以确定用户、无需额外 AEAD length 故性能更优 - 建议开 XTLS 避免二次加解密（native/xorpub 可自动 ReadV/Splice），可再叠上 XHTTP、WS 等传输层，详见 https://github.com/XTLS/Xray-core/pull/5067

适合机场的 VLESS Route： - 允许在分享给客户端的 UUID 中自定义第 7、8 个字节 - 服务端路由设置 vleesRoute 以匹配它们、分流不同出口，详见 https://xtls.github.io/config/routing.html#ruleobject

利好 iOS 的 客户端性能提升： - Tunnel/Socks/HTTP 入站去掉了 pipe 及其内置缓存，Xray-core 运行效率更高、占用内存更少，详见 https://github.com/XTLS/Xray-core/pull/5067#issuecomment-3236833240

Xray-core v25.9.5 相较于 v25.8.31： - 修复了延迟问题 https://github.com/XTLS/Xray-core/commit/fd54b10d976dffa184d978d37989eb5120b473f2 、用户流量统计问题 https://github.com/XTLS/Xray-core/commit/d20397c15d59eff5e991423a9550fa9abc6eeefd - VLESS 入站也去掉了 pipe 及其内置缓存 https://github.com/XTLS/Xray-core/pull/5076 - 新增了 ./xray vlessenc 指令 https://github.com/XTLS/Xray-core/pull/5078 - 以及其它的一些修复与改进
