feat: §10 온도 역전 판정 (TempProfileJudge)

- TempProfileJudge(순수함수): 조성 트레이 A,B,C 단조검증 → 정상/약화/프로파일붕괴/온도역전/입력부족 (tolInv 0.5, warn 0.5, collapse 0.3)
- 엔진 JudgeTempProfile: temp_tags 마지막(탑정 D=환류 서브쿨 오염) 제외, spanRef 최초정상 시드, 역전/붕괴 시 front trim HOLD
- AdvisoryResult.{TempProfileState,InversionPair,TempSpan,TempSpanRef} + 컨트롤러 노출
- 단위 6건(37/37). 후속: ApplyRecovery sigInv 연동 + 코러보레이션(센서vs공정)
