Subject: [PATCH] fix: resolve md-render --edit functionality and add enhanced
 version tracking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit fixes the critical md-render --edit regression that was causing
"blue box, no content" issues and adds comprehensive version tracking.

Key fixes:
- Fixed JavaScript newline escaping in f-string templates (\\n\\n not \\\\n\\\\n)
- Restored proper content rendering with marked.js CDN and graceful fallback
- Removed problematic validation logic that was blocking content display
- Cleaned up html-inject-editing command and related experimental code

Enhancements:
- Added version display in edit mode header with git commit and timestamp
- Enhanced version tracking to show local uncommitted changes with timestamps
- Added comprehensive regression tests to prevent future breakage
- Improved error handling and recovery mechanisms

The md-render --edit functionality now works reliably with full version visibility.
