Implement line ending preservation and address CLAUDE comments

- Fix server-side line ending preservation in plain mode by updating basehandler
  to not add protocol delimiters, preserving original CRLF/LF line endings
- Add comprehensive documentation to ProcessLine methods in all processors
- Remove all CLAUDE comments and replace with proper function documentation
- Update DCat test to include --quiet flag for cleaner server output
- Clean up PGO script and report files from scripts directory
- Improve code formatting and consistency across processor files
