llama.cpp b11699 修复 HTTP 代理支持
原标题：b11699
AI 摘要
llama.cpp 发布 b11699 版本，主要修复了 common_http_client() 忽略标准代理环境变量的问题，使 -hf 等下载功能在 HTTP 代理环境下不再静默失败。新版本支持 HTTPS_PROXY/HTTP_PROXY、NO_PROXY，并对格式错误的代理 URL 发出警告，同时强制对 localhost、127.0.0.0/8、::1 等回环地址绕过代理，避免 CLI 与本地 server 通信时卡在“Loading model...”。此外还提供了 macOS、Linux、Android、Windows 等多平台预编译包。
