[Bug] Text rendering has justified word spacing — unreadable output

[randomm]

Problem

Text output in oclite has two readability issues:

1. Justified Word Spacing

Words are spread across the full terminal width with huge gaps between them, as if text is being justified (like CSS text-align: justify).

2. No Left/Right Margins

Text runs edge-to-edge with no breathing room. Need left and right margins (e.g., 2-4 chars) to make content more readable and visually balanced.

Screenshot

See conversation — the output shows:

• Session Initialized ✓ line has huge gaps between words
• Bullet points like - 2 open PR s : db-setup .sql grants fix... are spread out
• Bold markdown text (**Key Constraints**) has broken spacing
• Tool output lines have inconsistent spacing
• No margins — text starts at column 0

Expected

• Normal left-aligned text with standard single-space word separation
• Comfortable left/right margins (2-4 characters)

Likely Cause

The wrap.ts or markdown.ts module is applying text justification or incorrect padding when wrapping lines to terminal width.

Key Files

• packages/opencode/src/cli/lite/wrap.ts — word wrapping with margins
• packages/opencode/src/cli/lite/markdown.ts — streaming markdown renderer
• packages/opencode/src/cli/lite/index.ts — output pipeline: write(wrap(pad(md.render(content))))

Acceptance Criteria

• Normal left-aligned text rendering (no justified spacing)
• Left margin of 2-4 characters on all output
• Right margin of 2-4 characters (wrap width reduced accordingly)
• Proper word boundaries preserved
• Bold/italic markdown renders without extra gaps
• Tool output in Live Block also has proper margins
• Readable output at any terminal width

Fixed in commit 0ce8c74 — fix(cli): fix justified text spacing by using comprehensive ANSI regex. Root cause: visible() function used incomplete ANSI regex that only matched color codes, causing non-color escape sequences to be counted as visible characters and producing incorrect line breaks.
