[action-translation] resync: lqcontrol.md

Forward Resync: lqcontrol.md

Source: QuantEcon/lecture-python.myst — lectures/lqcontrol.md
Source commit: a1353f0
This PR resyncs the translation to match the current source document.

Reason: The translation uses inline code (not NamedTuple-based) for the LQModel implementation, differing from the source's refactored NamedTuple/create_lq_model/simulate_and_plot approach, but this is largely a code structuring difference reflecting an older source version. More importantly, some source content is missing in translation: the note about notation not being universal ('some authors let Q be the matrix...') is dropped, the bullet about classical formulations using matrix decompositions with links to advanced:lu_tricks/classical_filtering is altered/shortened, and the exercise/solution labels lose some structure (e.g., 'lqc_ex1_solution' label removed). These are substantive content omissions requiring re-translation.

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 lqcontrol.md to match the current upstream (English) source document, restoring previously missing/altered explanatory content and updating structure/labels to the new source layout.

Changes:

• Re-synced headings and cross-references (including advanced lecture links) to match upstream naming and structure.
• Restored/updated mathematical notation and explanatory notes (e.g., the non-universal Q/R notation note).
• Updated exercises/solutions structure and labels (e.g., solution :label: fields) and refactored the main application code block to the upstream NamedTuple/helper-function pattern.

Summary: 翻译整体质量优秀，准确传达了原文关于LQ控制理论的技术内容，数学公式与代码块保存完好，专业术语翻译规范一致。存在少量可改进之处，包括维基百科链接来源的一致性以及个别术语表达的统一性，但均为次要问题，不影响整体理解和技术准确性。 数学公式和LaTeX代码块完整保留，编号引用（如{eq}lq_lom）均正确对应 专业术语翻译准确且与术语表高度一致，如'黎卡提方程'、'贝尔曼方程'、'确定性等价'等 长句拆分处理得当，逻辑连接词（如'因此'、'然而'、'具体来说'）使用恰当，保持了学术文本的严谨性和可读性 代码块中的注释准确翻译且保留了原有代码逻辑结构，变量名和函数名未做改动

Suggestions:

• 测度论链接：英文原文链接指向维基百科英文页面，中文翻译改为百度百科链接（https://baike.baidu.com/item/...），建议统一使用维基百科中文版链接以保持来源一致性，例如 https://zh.wikipedia.org/wiki/测度论
• 小标题层级：'### 添加交叉乘积项' 前多了一个空行，与其他小节的格式不完全一致（原文其他section标题前没有额外空行），建议检查格式统一性
• 示例2小节中'the household's current loss'译为'家庭当前的损失'，与其他地方'当期损失'的译法略有出入，建议统一术语为'当期损失'以保持全文一致性

Policy decision on the review's first suggestion (measure-theory link): Baidu Baike is an acceptable substitute for Wikipedia links in zh-cn editions, given better accessibility in mainland China (Matt, 2026-07-22). No change needed here; recorded in the program decision register so future reviews don't re-flag localised link substitutions.
