Wrap or unwrap text to any line length. Re-flow paragraphs, fix line breaks, format for fixed-width display.
Text wrapping reformats paragraphs to fit a fixed character width per line. This is useful for email formatting (many clients still prefer 72-80 char lines), plain text files, source code comments, and README files. Unwrapping removes all line breaks to create a single flowing paragraph.
Hard wrap mode breaks lines even in the middle of words (useful for terminal display). Soft wrap (default) breaks only at word boundaries to keep words intact.
