容器启动时
InitTokenEncoders()会从openaipublic.blob.core.windows.net下载 tiktoken 编码文件，在无外网环境下导致 FATAL 报错并退出。改动
builder2阶段用wget预下载两个编码文件，按 tiktoken-go 的缓存命名规则（SHA1(url)）存入/tiktoken_cache/：cl100k_base.tiktoken（gpt-3.5-turbo / gpt-4）o200k_base.tiktoken（gpt-4o）/tiktoken_cache复制进最终 Alpine 镜像ENV TIKTOKEN_CACHE_DIR=/tiktoken_cache，tiktoken-go 启动时直接读取本地文件，跳过网络请求我已确认该 PR 已自测通过，相关截图如下：
（离线环境无网络访问，容器可正常启动，不再出现
failed to get gpt-3.5-turbo token encoderFATAL 错误）
