Adds xurl (https://github.com/openclaw/xurl) as a third X search
backend, sitting after xAI API and Bird/GraphQL in the priority chain.
xurl uses the official X API v2 with OAuth2+PKCE authentication,
requiring only a free X Developer App. It auto-refreshes tokens and
works reliably as a stable fallback when xAI API key or browser
cookies are not available.
Limitations:
- X API search/recent returns last 7 days only (vs Bird's full archive)
- No AI-powered relevance scoring (uses token_overlap_relevance instead)
- Free tier: 180 requests per 15-minute window
New files:
- scripts/lib/xurl_x.py: xurl CLI wrapper with search + parse
- tests/test_xurl_x.py: 30 unit tests (all passing)
Modified files:
- scripts/lib/env.py: detect xurl in get_x_source_with_method(),
get_missing_keys(), and get_x_source_status()
- scripts/last30days.py: add xurl_x import and xurl branch in
_search_x() priority chain
- SKILL.md: document xurl setup option
