AEO Audit Tool — Genesis SEO + AEO Intelligence System
=======================================================
Audits a tradie business for Answer Engine Optimisation (AEO) readiness.
Checks how visible the business is when AI engines (Perplexity, ChatGPT,
Gemini, Claude) answer queries like "find me a plumber in Brisbane".

Usage:
    python aeo_audit.py --business "Smith Plumbing" --suburb "Brisbane" \
                        --trade "plumber" --website "https://smithplumbing.com.au"

    python aeo_audit.py --business "ABC Electrical" --suburb "Parramatta" \
                        --trade "electrician"

Output:
    - AEO Score 0–100
    - Gap list with severity (CRITICAL / HIGH / MEDIUM / LOW)
    - Prioritised fix list
    - Professional report saved to reports/aeo_report_<business>.md
