sub2api使用5.5进行compact步骤

根据GPT5.5在触发上下文压缩的时候报错404了，这个是OpenAI上游的问题还是sub2的问题呢？ · Issue #1865 · Wei-Shaw/sub2api · GitHub 这个issue的评论，把codex_cli_rs/0.104.0改成codex_cli_rs/0.124.0 及以上可以修复使用5.5进行compact报404找不到模型的问题。让GPT写了以下脚本进行一键修复。

# 安装 strings 所需工具，如果已经有会跳过
if ! command -v strings >/dev/null 2>&1; then
  if command -v apt >/dev/null 2>&1; then
    sudo apt update
    sudo apt install -y binutils
  elif command -v yum >/dev/null 2>&1; then
    sudo yum install -y binutils
