      • If re-fetch → run with --force
      • If use cached → inform user of location, done
    • Success (path printed) → inform user: "Documentation saved to <path>"
    • NOT_FOUND: → Use AskUserQuestion: "Library not found in Context7. How should I proceed?" with options like retry with different name, skip, etc.
    • RATE_LIMITED: → inform user rate limit hit, stop
