feat(v3.2): DailyLedger + RiskGate + news_snapshot + backtest_runner

- DailyLedger: 당일 매수 회계 + 연속 손절 카운터 + 매수 신호 점수 한 객체로 집약 (bot.py 정리)
- RiskGate: 테마당 동시 보유 + 노출 비율 상한 검증 (포트폴리오 레벨)
- news_snapshot: 뉴스 SQLite 영구 저장 + 사후 감성 재검증 인프라
- backtest_runner: 전 종목 KIS 일봉 기반 백테스트 (Sharpe/MDD/Calmar)
- bot.py 274 line 정리 (DailyLedger 분리)
- backtest.py 173 line 재작성 (v3.2 next-bar 체결 + 거래세)
- daily_launcher.py 폐기 (warmup_and_restart 통합)
- .gitignore: .claude/ 제외
