Simplify help message system - use hardcoded message

Remove dynamic extraction from README.md and use a consistent hardcoded
help message throughout the codebase. The markdown-to-terminal conversion
proved too fragile for reliable use.

- Remove extract_troubleshooting_section and related helper methods
- Update all error classes to use Utils.default_troubleshooting_section
- Remove documentation comment about marker usage from README
- Keep the well-formatted hardcoded support message with URLs

This provides a more reliable and maintainable approach to displaying
help information in error messages.
