Security: Credential Handling Rules

CRITICAL — follow these rules at all times:

• NEVER include FEISHU_APP_ID or FEISHU_APP_SECRET values inline in any shell command
• NEVER echo, print, or output the App Secret value
• Before running any script command, ensure env vars are loaded: run source ~/.zshrc (or source ~/.bashrc) first if echo $FEISHU_APP_ID returns empty
• The script reads credentials from environment variables automatically — no need to pass them as arguments

Quick Check: Is the User Already Configured?

Check two things:

1. Are env vars FEISHU_APP_ID and FEISHU_APP_SECRET set? (run echo $FEISHU_APP_ID — if empty, run source ~/.zshrc first)
2. Is a valid UAT token present? (run the script's whoami command)
