[action-translation] resync: linear_models.md

Forward Resync: linear_models.md

Source: QuantEcon/lecture-python.myst — lectures/linear_models.md
Source commit: 089e35c
This PR resyncs the translation to match the current source document.

Reason: Target includes extra font-configuration code (matplotlib font setup with FONTPATH, figure size defaults) not present in source's import cell. Otherwise content is faithfully translated with only minor i18n differences (e.g., link targets to Baidu Baike instead of Wikipedia for 'martingale' and 'multivariate normal distribution', which convey equivalent meaning). No missing content from source was found otherwise.

Changes

Whole-file resync applied. The entire document was resynced in a single pass.

Pull request overview

This PR forward-resyncs the Chinese translation of lectures/linear_models.md to match the current upstream source document, while preserving the repo-specific Matplotlib font configuration noted in the PR description.

Changes:

• Added translation metadata in the document front matter (title + heading map) and normalized several MyST/Jupytext code-cell directives (e.g., ipython3, :tags: style).
• Applied a broad set of small Markdown/typography adjustments (e.g., emphasis formatting, spacing around labels/blocks) consistent with the resynced source.
• Updated one code-cell expression to compute the normal scale via np.sqrt(Sigma_y.item()) when plotting the stationary distribution density.

Summary: 整体翻译质量优秀，准确传达了原文的技术内容和数学概念，专业术语使用规范，格式保留完整无语法错误。个别外部链接被替换为百度百科而非维基百科对应页面，建议核实链接内容的对应性；另有个别标点风格不统一及断句可优化之处，但均为小问题，不影响整体理解和学术严谨性。 数学公式、代码块和LaTeX标记全部完整保留，未出现格式错误 专业术语翻译准确且与术语表高度一致，如'鞅差序列'、'协方差平稳'、'伴随矩阵'等 长难句的拆分和重组处理得当，保持了学术文本的严谨性和可读性 代码注释和图表标签（如'时间'、'相对频率'）翻译恰当且符合语境

Suggestions:

• 移动平均表示部分: '鞅' 链接使用百度百科链接（https://baike.baidu.com/item/%E9%9E%85/56830519）替代了原文的维基百科链接，虽然内容准确但与源文档引用来源不一致，建议保留原始维基百科链接或说明替换理由
• 分布部分: '众所周知' 后的链接同样替换为百度百科链接（矩阵正态分布），而非维基百科的仿射变换页面，链接目标与原文略有偏差，建议核实链接内容与原文'Affine transformation'描述是否完全对应
• 全局稳定情况部分: '这就是全局稳定情况——更多理论内容请参见' 使用了破折号'——'而原文使用'---'，建议统一破折号风格以保持全文一致性（其他地方多使用' --- '空格加三连字符）
• 联合分布部分: '回想\n\n联合密度与条件密度存在如下关系' 这里换行略显突兀，原文是'recall that joint and conditional densities are linked by the rule'一气呵成的句子，建议合并为一句以提高流畅度，例如'回想联合密度与条件密度之间存在如下关系'
