refactor: improve command-line help text formatting

- Consolidate flag variants in help output (e.g. -c, --config)
- Use -- prefix for long form flags
- Remove configuration examples from help text
- Keep short form flags with - prefix
- Maintain all existing flag functionality

The help text is now more concise while preserving all command-line options.
