Testing the publish script

This is a test post to demonstrate the new publishing workflow.

Writing is now simple:

• Create a markdown file in src/posts/
• Run ./publish src/posts/filename.md
• Done

Features:

• Markdown to HTML conversion
• Automatic date extraction from filename
• Image handling (auto-copy to /img)
• Inserts at top of writing section (newest first)

The site stays pure - no build step, no JavaScript. Just a convenience script for writing.
