"""X (Twitter) search via xurl CLI — official X API v2 with OAuth2.

xurl is an open-source CLI for the X API (https://github.com/openclaw/xurl).
It uses OAuth2 with PKCE and automatic token refresh, requiring only a free
X Developer App. No xAI subscription or browser cookies needed.

Install: npm install -g xurl
Auth:    xurl auth oauth2 login

Priority: xAI API > Bird/GraphQL > xurl > web-only fallback
