Summary: 新增章节的翻译整体质量很高，准确传达了原文的数学推导与经济学论证，术语使用规范统一，MyST/Markdown 格式与代码块完整无误，仅存在少量可进一步打磨的措辞问题，不影响理解。 数学公式、代码块与 MyST 指令格式在所有新增章节中均完整保留，未见语法错误 专业术语（黎卡提方程、协态、特征值、横截面分布等）翻译准确且前后一致 长难句的切分与中文表达流畅自然，较好地保留了原文的逻辑层次和学术语域

Suggestions:

• [minor · fluency] lectures/lq_mean_field_games_extensions.md — What we need from the previous lecture: “在那一讲中，我们研究了一个由连续多个主体组成的经济体”将原文“a continuum of agents”翻译为“由连续多个主体组成的经济体”，略显意译，但未改变含义，属轻微风格问题。 → 可改为“我们研究了连续统的一组主体”以更贴近原文的测度论含义。
• [minor · terminology] lectures/lq_mean_field_games_extensions.md — Coupling through higher moments: “柯尔莫戈罗夫前向方程”一词未在术语表中列出对应译法，但属于标准译名，建议保持一致性检查（文中其余部分未出现该术语，无法比对一致性，但确认译法准确）。
• [nit · fluency] lectures/lq_mean_field_games_extensions.md — When the restriction fails: “同样的方法也可以处理主体无法控制的状态变量”一句衔接“## Forcing processes and pass-through”标题后的首句，略显生硬，可考虑增加连接词以提升可读性。 → “同样的方法也可以用于处理主体无法控制的状态变量，例如边际成本。”

🔵 Needs a closer look

The companion revision to the Chinese lq_mean_field_games.md is missing, leaving the original lecture out of sync with the English source, which needs human judgment to confirm or resolve.

What changed in this PR

This PR is an automated translation sync that ports QuantEcon/lecture-python.myst#1096 into the Chinese (zh-cn) book. It adds a new lecture, 线性二次均值场博弈：扩展 (LQ Mean Field Games: Extensions), covering state-action cross terms, forcing processes/pass-through, and coupling through higher moments, and wires it into the book's table of contents and bibliography.

Changes:

• Adds the new translated lecture lq_mean_field_games_extensions.md plus its translation-state file.
• Registers the lecture in _toc.yml (after lq_mean_field_games).
• Adds four bibliography entries (Hayashi1982, CooperHaltiwanger2006, BenhabibFarmer1994, BallRomer1990) referenced by the new lecture.

File	Description
lectures/​lq_mean_field_games_extensions.md	New translated lecture; headings map, cross-refs ({ref}/{prf:ref}/{eq}) and citations all resolve; code cells preserved verbatim.
lectures/​_toc.yml	Adds the new lecture entry (line 175); also introduces an unrelated trailing-whitespace change on a caption line (line 33).
lectures/​_static/​quant-econ.bib	Adds four well-formed bib entries used by the new lecture.
.translate/​state/​lq_mean_field_games_extensions.md.yml	New sync-state file; fields/values consistent with existing state-file conventions.

A notable cross-file concern: source PR #1096 also substantially revised the original lq_mean_field_games.md (part of the "split into two lectures"), and this PR's sync metadata lists that file, but the Chinese lq_mean_field_games.md is not updated here and still points to the older source-sha — so it is now out of sync with the English source that the new lecture refers back to.
