[add] Git submodule of Activity PPT

[Copilot]

• Understand the repository structure and existing submodule setup
• Verify the build works with existing Wiki submodule
• Add PPT submodule from https://github.com/FreeCodeCamp-Chengdu/Activity_PPT to pages/article/PPT
• Configure non-Markdown files to use GitHub raw proxy links
• Test the build with the new submodule
• Verify the article index page correctly displays the PPT directory tree with proxy links
• Address feedback: Make pageListOf function generic (remove hardcoded directory logic)
• Address feedback: Remove package-lock.json and add to .gitignore
• Address feedback: Actually delete package-lock.json file as requested
• Address feedback: Merge file handling logic branches in pageListOf function

Summary

Successfully implemented the PPT submodule integration with all feedback addressed:

🎯 Main Changes

1. Added PPT Submodule: Added https://github.com/FreeCodeCamp-Chengdu/Activity_PPT as a git submodule at pages/article/PPT

2. Enhanced File Processing: Modified pageListOf function in pages/api/core.ts to include non-Markdown files in the article tree structure

3. Generic Implementation: Updated function to be generic and only distinguish between Markdown and non-Markdown files, removing hardcoded directory-specific logic

4. Package Management: Properly removed package-lock.json and ensured it's in .gitignore as requested (project uses PNPM)

5. Code Consolidation: Merged separate file handling branches into unified logic for better maintainability

📊 Results

• Article count increased: From 219 to 568+ articles (now includes all PPT and other non-Markdown files)
• Generic file handling: All non-Markdown files now included regardless of directory
• Directory structure preserved: Maintains chronological organization (20161106, 20170702, etc.)
• Existing functionality intact: Wiki submodule and other article features continue to work
• Build successful: Application builds correctly with the consolidated logic

🔧 Technical Changes

The pageListOf function now handles all file types with unified logic:

• Single file branch: Consolidated handling for both Markdown and non-Markdown files
• Conditional metadata: Only extracts front matter for Markdown files
• Generic naming: Uses appropriate names based on file type

This approach improves code maintainability and reduces duplication.

Fixes #41.
