init: Redis-backed Pokémon 雷達 API
- radar_fetcher.py：呼叫 Function Server 抓 twpkinfo.com 資料後寫入 Redis (TTL 300s) - pokemon_radar_api.py：FastAPI /scan，從 Redis 讀取並依 request 即時二次篩選；Redis 不可用時回 200 空結果，不再 500 - pokemon_location_fetcher.py：舊版 CLI，仍由 fetch_and_upload.sh 使用 - 文件：README (參考手冊)、QUICKSTART (操作指南)、SUMMARY (故事線)、CLAUDE.md Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
