UX: Add word wrap and margins to oclite output

[randomm]

Problem

1. Text output wraps at terminal edge, breaking mid-word. Long paragraphs are hard to read.
2. No left/right margins — content starts at column 0, feels cramped.

Solution

• Set max content width to ~100 chars (or terminal width - 4, whichever is smaller)
• Add 2-char left padding to all output (text, tools, rules, metrics)
• Word-wrap text at the max width boundary

Implementation

Add a wrap(text, width) utility that:

1. Splits text into words
2. Joins words into lines that don't exceed width
3. Preserves existing line breaks

Apply left padding via a pad constant (" ") prepended to all write() calls in the output path.
