I Luk Kim 8c9abe3e31 feat(attention): Attention 서브시스템 추가 — 이벤트 중심 Wikipedia/GDELT 관심도 피처 
## 주요 기능
- Entity resolver: ticker → canonical name → Wikipedia 매칭
  - SEC company_tickers.json fallback으로 placeholder name 자동 수정
  - all-caps SEC 이름 title-case 변환, "Com" suffix 처리
- Wikipedia 페이지뷰 수집 + spike_10d / zscore_20d 피처 계산
- GDELT V2 DOC API 뉴스 기사 수집 (2017-01-01 이후)

## GDELT rate limit 제약 강제
- /event/{ticker} 온디맨드 GDELT 수집 제거 (IP ban 방지)
- 프로세스 전역 asyncio.Lock + 10초 최소 간격 강제
- 429 시 exponential backoff (30→60→120s)
- news.gdelt_status 필드로 클라이언트에 수집 상태 명시
  ('collected' | 'not_collected' | 'not_available')

## API
- GET  /api/v1/attention/event/{ticker}?event_date=YYYY-MM-DD
- GET  /api/v1/attention/entity/{ticker}
- POST /api/v1/attention/admin/resolve/{ticker}
- POST /api/v1/attention/admin/collect/wiki/{ticker}
- POST /api/v1/attention/admin/collect/gdelt/{ticker}  ← scheduler 전용

I Luk Kim b88835cded feat(screener): add stock screener API with yfinance EquityQuery

for condition-based stock filtering without manual web searches.

- app/services/screener_service.py: ScreenerService wrapping yfinance screen()
  via run_in_executor; exchange mapping (NYSE→NYQ, NASDAQ→NMS/NGM/NCM, etc.);
  btwn/gt/lt/is-in/eq EquityQuery builder; post-filter for ETF/FUND exclusion
- app/api/v1/endpoints/screener.py: /stocks (with_cache TTL=300) + /fields metadata
- app/api/v1/api.py: register screener router at prefix /screener
- app/main.py: add screener OpenAPI tag and HTML doc section with examples

I Luk Kim bf6932ca2f Add Alpaca-specific DB table and Redis caching for Alpaca/FINRA endpoints 
Separate Alpaca price data into dedicated AlpacaPriceData table to avoid
UniqueConstraint('ticker', 'date') conflicts with Yahoo Finance PriceData.
Add Redis caching (build_cache_key/get_cached_response/set_cached_response)
to 3 Alpaca endpoints and 2 FINRA query endpoints with appropriate TTLs.
