Add FRR anycast lab: HLD, containerized topology, docs

Реализует HLD-дизайн (hld.md) в виде развёртываемого Docker Compose окружения: 5 FRR-роутеров (A1-A3 anycast 10.200.200.1/32 на AS 65001, B1/B2 на AS 65002/65003) + 6 клиентских контейнеров, ECMP-балансировка трафика клиентов площадки B к anycast-адресу площадки A. - docker-compose.yml, frr/*, entrypoints/* — топология и конфиги FRR - scripts/verify.sh, scripts/traffic-test.sh — проверка BGP/ECMP и трафика - hld.md — HLD-дизайн + Mermaid-диаграмма топологии - README.md — запуск, структура, команды проверки на роутерах и клиентах - docs/ — планы внедрения и summary по каждому изменению Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Bc3HkMiDwooSyLBLoMKNyF
