Improve markdown-to-terminal conversion to preserve URLs

- Update convert_markdown_to_terminal to preserve URLs in links
  - Changed link conversion from "[text](url)" to "text: url" format
  - Headers (H1-H6) now properly converted with emoji prefix
  - Removed redundant Professional Support cleanup
- Add documentation comment to README.md explaining marker usage

This ensures users can access actual URLs in error messages, making
support resources more accessible.
