chanjing-credentials-guard

Run this skill before any chanjing-related action. When the user asks to generate or configure chanjing credentials/keys (AK/SK), run this skill to guide them—check if already configured; if yes, ask whether to re-apply; then open login page and let the user either run the config command or paste AK/SK for the agent to apply. ALWAYS run when user asks for chanjing credentials/keys or before any chanjing API (voice list, TTS, avatar, voice-clone).
