v1.3.1

Fixed

• MDX Compilation Errors: Resolved multiple "Unexpected character" and "End-tag mismatch" errors in LeetCode solution pages that were preventing the Docusaurus build.
• JSX Syntax Sanitization:
  • Escaped comparison operators (<= and >=) in Markdown text to prevent them from being misinterpreted as JSX tags.
  • Converted legacy HTML tags (<pre>, <strong>, <em>, <code>, <ul>, <li>, <p>, <div>) to standard Markdown syntax across all LeetCode pages (page-1.mdx to page-5.mdx).
• Docusaurus Build Stability:
  • Replaced <pre> blocks with Markdown code blocks (```text) for better rendering and MDX v2 compatibility.
  • Ensured proper spacing between block-level elements to satisfy MDX parser requirements.
• Multilingual Consistency: Applied identical syntax fixes to both English (docs/docs/) and Russian (docs/i18n/ru/) documentation sets.
