What changed in this PR

This PR is an automated translation sync from the upstream QuantEcon/test-translation-sync repository (source PR #988). It updates the Farsi translation lecture.md to reflect changed code-cell comments/titles in the English source, and adds a per-file translation state record. The changes are confined to translated code-comment/title strings and tracking metadata, with no logic or structural changes.

Changes:

• Updates four translated code-cell comments/titles in lecture.md (two inline # comments, one ax.set_title, one print label).
• Adds .translate/state/lecture.md.yml recording sync metadata (source-sha, synced-at, model, mode, section-count, tool-version).

File	Description
lecture.md	Refreshed Farsi translations of code-cell comments and plot/print titles to match the updated English source.
.translate/​state/​lecture.md.yml	New state file capturing the sync metadata for lecture.md.

Notes:

• The new state file is internally consistent: source-sha matches the PR metadata sourceCommitSha, synced-at: "2026-10-09" matches the current date (not a future date), mode: UPDATE is appropriate for an existing file, and section-count: 3 matches the 3 top-level translation.headings keys (without ::) in lecture.md.
• The translated comment/title changes are coherent and remain inside code cells, with no structural or code-logic impact.

📝 Translation Quality

Criterion	Score
Accuracy	9/10
Fluency	9/10
Terminology	9/10
Formatting	10/10
Overall	9.2/10

Summary: The modified sections (Vector Spaces, Applications in Economics, Matrix Operations) are translated accurately and fluently, with correct preservation of all math, code, and MyST formatting. Terminology aligns well with the glossary (e.g., معکوس لئونتیف, ماتریس انتقال). Minor stylistic improvements could be made to a couple of sentences for better natural flow, but no accuracy or structural issues were found. Mathematical notation, code blocks, and LaTeX equations are preserved perfectly across all modified sections Economic and linear algebra terminology (Leontief inverse, input-output matrix, eigenvalue/eigenvector) consistently matches the reference glossary Code comments are naturally and accurately translated without altering functional code

Suggestions:

• [minor · terminology] lecture.md — #### کاربردها در اقتصاد (Vector Spaces section): The phrase 'existence of additive identity' and 'existence of additive inverses' use 'هویت جمعی' for 'additive identity', which is understandable but a more standard academic term would be 'عنصر همانی جمعی' or 'خنثی جمعی'. This is a minor terminology nuance, not a glossary violation, but could improve precision. → وجود عنصر خنثی جمعی (بردار صفر)
• [minor · fluency] lecture.md — #### کاربردها در اقتصاد (Vector Spaces > Applications in Economics): The sentence 'ترکیب‌های تخصیص‌های امکان‌پذیر، امکان‌پذیر باقی می‌مانند' repeats 'امکان‌پذیر' awkwardly close together, which slightly reduces readability compared to the smoother English original. → ترکیب تخصیص‌های شدنی همچنان شدنی باقی می‌ماند
• [nit · fluency] lecture.md — ## عملیات ماتریسی - 'حاصل‌ضرب AB نشان‌دهنده اعمال تبدیل B و سپس تبدیل A است': Translation is accurate but slightly literal; a more natural academic Persian phrasing could improve flow without changing meaning. → حاصل‌ضرب AB به معنای اعمال ابتدا تبدیل B و سپس تبدیل A است
