Modern CV自定义线条需求：将灰色线条宽度调整至与页边距一致并在其上方添加章节

需求1：调整灰色线条宽度与文档页边距一致 #

默认的casual风格中，标题下方的灰色线条宽度是固定值，没有适配文档的正文宽度（也就是页边距内的有效宽度）。我们可以通过重新定义\makecvtitle命令里的线条生成逻辑，把线条宽度设置为\textwidth，让它和页边距完全对齐。

需求2：在灰色线条上方插入章节 #

要在标题和灰色线条之间插入章节，我们需要修改\makecvtitle的结构，在输出线条之前添加自定义的章节内容。这里直接用\section命令插入即可，也可以根据需求选择无编号的章节格式。

修改后的完整LaTeX代码 #

\moderncvstyle{casual} 
\moderncvcolor{grey} 
\usepackage[USenglish]{babel}
\usepackage{lipsum} 
\usepackage[scale=0.75]{geometry} 

% 重新定义makecvtitle，同时实现两个定制需求
\renewcommand*{\makecvtitle}{

  % 需求2：在灰色线条上方插入自定义章节（这里示例为职业概述）
  \section{Professional Summary}
  \cvitem{}{A results-driven finance professional with expertise in risk analysis and derivatives trading, seeking to leverage analytical skills in a dynamic financial environment.}

关键修改说明 #

1. 线条宽度适配：
   用\rule{\textwidth}{0.4pt}替换了原命令中固定宽度的线条，\textwidth代表文档正文的有效宽度（即页边距以内的区域），确保线条完全贴合页边距。

2. 章节插入位置：
   在重新定义的\makecvtitle中，我们在输出灰色线条之前添加了\section{Professional Summary}及对应内容，让这个章节恰好出现在标题和线条之间。如果不需要章节编号，可以改用\section*{Professional Summary}生成无编号章节。
