feat: 완전한 자재 분류 시스템 v2.0 구축 완료

Browse Source 
🎯 주요 성과:
- 8개 주요 자재군 완전 분류 시스템 구축
- 재질 분류 엔진 + 개별 자재별 특화 분류
- 스풀 관리 시스템 (파이프 절단 계획용)
- 실제 BOM 데이터 기반 설계 및 테스트

📁 새로 추가된 자재 분류 시스템:
- app/services/pipe_classifier.py (파이프 + 스풀 관리)
- app/services/fitting_classifier.py (피팅 10가지 타입)
- app/services/flange_classifier.py (플랜지 SPECIAL/STANDARD)
- app/services/valve_classifier.py (밸브 단조/주조 구분)
- app/services/gasket_classifier.py (가스켓 8가지 타입)
- app/services/bolt_classifier.py (볼트/너트/와셔 통합)
- app/services/instrument_classifier.py (계기류 기본)

🔧 분류 성능:
- PIPE: 제조방법, 끝가공, 스케줄, 절단계획
- FITTING: 타입, 연결방식, 압력등급, 제작방법
- FLANGE: SPECIAL(10종)/STANDARD(6종), 면가공
- VALVE: 9가지 타입, 단조/주조 구분, 작동방식
- GASKET: 8가지 타입, 재질별, 온도/압력 범위
- BOLT: 체결재 3종, 나사규격, 강도등급

📊 기술적 특징:
- 정규표현식 기반 패턴 매칭 엔진
- 신뢰도 점수 시스템 (0.0-1.0)
- 증거 기반 분류 추적 (evidence tracking)
- 모듈화 구조로 재사용성 극대화
- 실제 DAT_FILE + DESCRIPTION 패턴 분석

🎯 분류 커버리지:
- 재질: ASTM/ASME 표준 + 특수합금 (INCONEL, TITANIUM)
- 제작방법: FORGED, CAST, SEAMLESS, WELDED 자동 판단
- 압력등급: 150LB ~ 9000LB 전 범위
- 연결방식: BW, SW, THD, FL 등 모든 방식
- 사이즈: 1/8" ~ 48" 전 범위

💾 데이터 통합:
- 기존 materials 테이블과 완전 호환
- 프로젝트/도면 정보 자동 연결
- 스풀 정보 사용자 입력 대기 (파이프만)
- 구매 정보 자동 생성 (공급업체, 납기)

🧪 테스트 완료:
- 각 시스템별 10+ 테스트 케이스
- 실제 BOM 데이터 기반 검증
- 예외 상황 처리 테스트
- 신뢰도 검증 완료

Version: v2.0 (Major Release)
Date: 2024-07-15
Author: hyungiahn
