🎉 Release v1.1.0: Editorials CMS & Problems Hub Re-architecture

This release represents a massive structural upgrade to the Learning Portal’s Problem Tracking infrastructure. We have completely decoupled rigid inline solutions into a dedicated CMS database, added dynamic URL tracking, and modernized the UI.

🚀 Major Features & Updates

1. The Decap CMS Editorials Pipeline (_editorials/)

• Automated Solutions Extraction Workflow: Programmatically stripped hundreds of legacy inline anchors (#minimum-window-substring) embedded within massive *-problems.md markdown pages.
• Dedicated CMS Collection: Ported all extracted standalone solutions and embedded notes into a brand new _editorials/ Jekyll collection natively hooked up to the Decap CMS Admin dashboard.
• Frontmatter Injection: Dynamically injected precise YAML frontmatter (ex: problem_id, date, title) into all recovered .md and .cpp solutions to allow CMS parsing.

2. Problem Hub UI Deduplication Engine

• Intelligent URL Sniffing: Rewrote the DOM Generation script (problems.js) to actively read the file extensions of incoming database links (e.g. .pdf, .cpp, .com) to automatically generate perfect semantics.
• Dynamic Buttons: The Hub now accurately assigns graphical buttons such as 📝 PDF Notes, 💻 Raw Code, 📖 Editorial, or 🔗 External Link based purely on the string path.
• Cloned Link Scrubbing: Ran a global deduplication script across the _data/problems.yml schema to aggressively delete any duplicated strings where solution_url perfectly matched approach_url. The UI now seamlessly combines dual-format materials without rendering double buttons.

3. Cross-Domain Authentication Fixes

• Git Gateway Config Repairs: Fixed the critical Netlify Identity configuration mismatch in admin/config.yml where Decap CMS was erroneously attempting to auth against the GitHub Pages subpath instead of the Netlify backend.
• Script Inject Order: Reordered the HTML <script> tags in admin/index.html to guarantee the Identity Token payload mounts before Decap CMS attempts to call the login endpoint.

4. System Documentation

• Editorials Insertion Guide: Built a canonical EDITORIALS_GUIDE.md manual instructing users exactly how to assign .md, .pdf, .cpp, or Leetcode links from both the Local Repository and Netlify CMS dashboard.
• Navigational routing hooked into the top of the Problems Hub for instant reading!
