v3.42.32: Add fatih/color for cross-platform terminal colors

- Windows-compatible colors via native console API
- Color helper functions: Success(), Error(), Warning(), Info()
- Text styling: Header(), Dim(), Bold(), Green(), Red(), Yellow(), Cyan()
- Logger CleanFormatter uses fatih/color instead of raw ANSI
- All progress indicators use colored [OK]/[FAIL] status
- Automatic color detection for non-TTY environments
