refactor(builder): extract ANSI colour formatting helpers

- Add colorize(), bold(), tableCell(), and tableBorder() helpers
- Refactor printLibraryList to use helpers instead of inline ANSI codes
- Separate content from presentation in table formatting logic
- Fix column alignment in library list output
