2026-05-10 — Initial codebase mapping

• Created .paul/codebase/ (stack, architecture, structure, conventions, testing, integrations, concerns, db_schema, tech_changelog)
• Why: bootstrap PAUL workflow; document the PrestaShop 1.7.8.11 install + custom Cross Sell PRO module before further work
• Impact: future phases reference these documents instead of re-exploring the codebase
