Quentin 3271fee5cc init: WordFileParse docx→HTML 解析服务(含 Word EQ 域公式修复)
服务:Spring Boot 3.2 + docx4j 8.3.9,POST /api/v3/server_office_file/file/parse
      接受 .docx,返回 HTML(公式 → LaTeX,图片 → RustFS 外链)

公式支持三类来源:
- OMML(Word 2007+ 公式)      → Python omml_mathml2latex
- MathType OLE 对象            → Ruby mathtype2mathml → MathML → LaTeX
- Word EQ 域(老教辅主力)      → EqToLatexUtil(本次新增)

本次改动:
1. 新增 java-svc/.../core/EqToLatexUtil.java:
   移植自 jby backend-services office-core,EQ 语法 → LaTeX
   (\f→\dfrac、\r→\sqrt、\i→\int/\sum/\prod、\s→^{}/_{}、\b→\left\right、
     \a→array、\x→\boxed/\overline、\o\al 堆叠、圈码、化学符号、极限、连等式)
   品牌标记 JBYU* → WPU*,与采集端一致
2. CtoMathFinder:接上 EQ 分支(原为 not-ported 桩),域代码经
   EqToLatexUtil.convert 转 LaTeX 写入 eqLatexMap(WPEQNUM 占位符)
3. WordParseUtil.dealPlaceholder:EQ 的 LaTeX 同样加 \( \) 包裹
   (原先因 WPEQNUM 例外不加包裹,前端/MathJax 不渲染)

修前症状:教辅 Word 里分式/方程组/上下标整段丢失(如 {−1/3, 1} 变成 {-,1})
修后实测:46 份教辅 2908 处 EQ 域全部还原,公式总数 2954 处、零未包裹残留

安全:application.yml(含 RustFS 密钥)不入库,提供 application.yml.example;
      OssService 的 @Value 默认密钥已清空

"""
Debug output control utility.
This module provides a centralized way to control debug output across the project.
Debug output is disabled by default and can be enabled via the OMML2TEX_DEBUG
environment variable.
Usage:
from omml2tex.utils.debug import debug_print
debug_print("[DEBUG] Some debug info") # Only prints if OMML2TEX_DEBUG=1
Environment Variables:
OMML2TEX_DEBUG: Set to "1" or "true" to enable debug output (default: disabled)
"""
import os
import sys
def is_debug_enabled() -> bool:
"""
Check if debug mode is enabled via environment variable.
Returns:
True if OMML2TEX_DEBUG is set to "1" or "true", False otherwise
"""
debug_value = os.environ.get('OMML2TEX_DEBUG', '').lower()
return debug_value in ('1', 'true', 'yes', 'on')
def debug_print(*args, **kwargs):
"""
Print debug output only if debug mode is enabled.
This function has the same signature as the built-in print() function,
but only outputs to stderr when OMML2TEX_DEBUG environment variable is set.
Args:
*args: Arguments to print
**kwargs: Keyword arguments for print (e.g., file, sep, end)
Examples:
>>> debug_print("[DEBUG] Processing equation")
>>> debug_print("[DEBUG] Value:", value, "Result:", result)
>>> debug_print("[DEBUG] Error", file=sys.stderr) # file=sys.stderr is default
"""
