# ============================================================================
#  Grok 注册机 - 一键启动脚本 (Linux / macOS)
#  自动检测并安装缺失环境，然后启动 register_cli.py
#
#  用法:
#    ./start.sh                          # 默认不限数量（持续注册）
#    ./start.sh --count 10               # 跑 10 个
#    ./start.sh --count 10 --threads 3   # 3 线程跑 10 个
#    ./start.sh --extra 5                # 在已有基础上再注册 5 个
#
#  首次运行会自动:
#    1. 安装 uv（如缺失）
#    2. 安装 Python 3.13（如缺失，经 uv 管理）
#    3. 同步 Python 依赖
#    4. 尝试安装 Chrome/Chromium（如缺失且有权限）
#    5. 从模板复制 .env / config.json（如缺失）
