chore: adopt vYYYY.MM.DD.HHMMSS.COMMIT versioning scheme

Change from v0.1.YYYYMMDD.HHMMSS.COMMIT to vYYYY.MM.DD.HHMMSS.COMMIT
to align with BizPrint versioning style:
- Semantic year.month.day separation via dots
- Preserves hourly precision (HHMMSS)
- Includes commit hash for traceability

Example: v2026.07.24.165410.7bd491e

+
+## 현재 상태
+- ✅ 코드: 모두 커밋됨
+- ✅ 테스트: 214/214 통과
+- ✅ 워크플로우: 준비 완료
+
+---
+
+## 배포 방법 (2단계)
+
+### 📍 1단계: Release 생성 (prepare-release.yml)
+
+**목적:** 코드를 빌드하고 Release 버전을 만드는 단계
+
+**URL 이동:**
+```
+https://gitea.taxbaik.com/kjh2064/QuantEngineByItz/actions
+```
+
+**작업 절차:**
+1. 위 URL에 접속
+2. 왼쪽 목록에서 "Prepare Release" 클릭
+3. 오른쪽 상단 "Run workflow" 버튼 클릭
+4. 팝업에서 파라미터 입력:
+
+   **파라미터: version (버전 이름)**
+   - **의미:** 이 Release의 이름
+   - **입력값:**
+     - **비워두기** (추천): 자동으로 `quant_20260724.0.xxxxx` 형태로 생성
+     - **직접 입력**: `v0.1.20260724` 같이 원하는 이름 입력
+   - **기본값:** (비어있음 = 자동 생성)
+
+5. "Run workflow" 클릭
+6. 실행 완료 대기 (약 5-10분)
+
+**완료 후:**
+- ✅ 빌드 성공
+- ✅ Release 생성됨
+- ✅ Git 태그 생성됨
+- ✅ 아티팩트 업로드됨
+
+---
+
+### 📍 2단계: 배포 실행 (deploy-prod.yml)
+
+**목적:** 생성된 Release를 운영 서버에 배포하는 단계
+
+**URL 이동:**
+```
+https://gitea.taxbaik.com/kjh2064/QuantEngineByItz/actions
+```
+
+**작업 절차:**
+1. 위 URL에 접속
+2. 왼쪽 목록에서 "Deploy to Production" 클릭
+3. 오른쪽 상단 "Run workflow" 버튼 클릭
+4. 팝업에서 파라미터 입력:
+
+   **파라미터: release (배포할 Release 선택)**
+   - **의미:** 1단계에서 만든 Release 중 어떤 것을 배포할지 선택
+   - **입력값:**
+     - **비워두기** (추천): 가장 최신 Release를 자동으로 배포
+     - **직접 입력**: 1단계에서 생성된 버전명
+       - 예: `v0.1.20260724`
+       - 예: `quant_20260724.0.abc1234`
+   - **기본값:** (비어있음 = 최신 Release 배포)
+
+5. "Run workflow" 클릭
+6. 실행 완료 대기 (약 3-5분)
+
+**자동으로 진행되는 작업:**
+1. Release 아티팩트 다운로드
+2. SSH로 서버에 전송
+3. 서버에서 압축 해제
+4. 기존 서비스 중지
+5. 새 버전 배포
+6. 서비스 시작
+7. 자동 헬스 체크 (6가지 항목 검증)
+
+---
+
+## 배포 후 확인
+
+**웹에서 확인:**
+```
+http://178.104.200.7/quantengine/Account/Login
+계정: admin
+암호: quant123!
+```
+
+**SSH로 상태 확인:**
+```bash
+ssh kjh2064@178.104.200.7
+
+# 서비스 상태 확인
+systemctl status quantengine
+
+# 최근 로그 보기 (실시간)
+journalctl -u quantengine -f
+
+# 배포된 버전 확인
+readlink ~/quantengine_active
+```
+
+---
+
+## 문제 발생 시 롤백
+
+**이전 버전으로 되돌리기:**
+
+```bash
+ssh kjh2064@178.104.200.7
+
+# 백업에서 복구
+ln -sfn $(readlink ~/quantengine_active_backup) ~/quantengine_active
+
+# 서비스 재시작
+sudo systemctl restart quantengine
+
+# 확인
+systemctl status quantengine
+```
+
+---
+
+## 예시 시나리오
+
+### ✅ 시나리오 1: 기본 배포 (추천)
+
+**1단계:**
+- "Prepare Release" 실행
+- version 파라미터: **비워두기** ← 자동 생성
+- 대기
+
+**2단계:**
+- "Deploy to Production" 실행
+- release 파라미터: **비워두기** ← 최신 Release 배포
+- 대기
+
+**결과:** 최신 코드가 운영 서버에 배포됨
+
+### ✅ 시나리오 2: 특정 버전 배포
+
+**1단계:**
+- "Prepare Release" 실행
+- version 파라미터: `v0.1.20260724` 입력
+- 대기 → Release "v0.1.20260724" 생성됨
+
+**2단계:**
+- "Deploy to Production" 실행
+- release 파라미터: `v0.1.20260724` 입력 ← 위에서 생성한 버전
+- 대기
+
+**결과:** 지정된 버전이 운영 서버에 배포됨
+
+---
+
+## 주의사항
+
+⚠️ **반드시 순서대로!**
+- 1단계(Prepare Release) 없이 2단계를 할 수 없음
+- 1단계 완료 후 2단계 실행
+
+⚠️ **파라미터 입력**
+- 오타 없이 정확히 입력
+- 존재하지 않는 버전을 입력하면 오류 발생
+
+⚠️ **배포 중 중단 금지**
+- 실행 중에는 중단하지 말 것
+- 전체 프로세스는 3-5분 소요
+
+---
+
+## 빠른 참조
+
+| 단계 | Workflow | 파라미터 | 권장값 |
+|------|----------|---------|-------|
+| 1 | Prepare Release | version | (비워두기) |
+| 2 | Deploy to Production | release | (비워두기) |
+
+**총 소요 시간:** 10-15분
