Snowflake Cortex Code CLI

先安装并配置 Cortex CLI，再运行 integrations/codex/install.sh 安装 cortexcode-tool。默认使用 RO 模式，按审批结果执行命令。

git clone https://github.com/Snowflake-Labs/subagent-cortex-code.git
cd subagent-cortex-code
bash integrations/codex/install.sh

# 先确认 Cortex CLI：
# which cortex
# cortex connections list

# 核对：
# cortexcode-tool --version
# cortexcode-tool --envelope RO "How many databases do I have in Snowflake?"

# 卸载：
# bash integrations/codex/uninstall.sh
