chore: استيراد أولي من سيرو (ecfe7568) — بلا أي تعديل

نسخة كاملة من مستودع سيرو عند ecfe7568 لتكون أساس تطبيق «انطلق». نُسخ المتعقَّب في git فقط (12,509 ملفاً / 302 م.ب) بـ git archive، لا `cp -r` — فاستُثنيت تلقائياً مخلفات البناء (build · node_modules · .dart_tool · .gradle · Pods ≈ 10.7 غ.ب) وكل ما يستثنيه .gitignore. هذا الكوميت **بلا أي تعديل عمداً** حتى يكون كل ما يليه فرقاً مقروءاً مقابل سيرو الأصلي. سيرو نفسه لم يُمسّ. ⚠️ لا يبني بعد: `.env` و`lib/env/env.g.dart` غير متعقَّبين في سيرو (وهذا صحيح — أسرار لكل مستأجر). كل تطبيق فلاتر هنا يحتاج .env خاصاً بانطلق ثم توليد env.g.dart عبر build_runner. لا تُنسخ أسرار سيرو.
