Agent Skills: integrate-mediacrawler

Audit, install for isolated non-commercial research, configure, or invoke the pinned NanmiCoder/MediaCrawler CLI with explicit platform, login, crawl scope, storage, and rate limits. Use only when the user explicitly names MediaCrawler or asks to connect that repository for authorized learning/research. Do not trigger for ordinary web research, social analytics, commercial monitoring, proxy rotation, or general scraping.
