The multi-line output previously wrapped only at info-block boundaries, pushing an entire block to the next line when it didn't fit and leaving unused space at the end of each line. Replace that with continuous character-fill wrapping: each line is filled to line_wrap_length before breaking, splitting in the middle of a block when needed. Add wrapAnsiText, which counts visible width (ignoring ANSI escape sequences), re-applies the active color at the start of each wrapped line so colors survive a mid-block break, and keeps emoji surrogate pairs intact. Remove the now-unused removeAnsiCodes helper. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PTMmeo1oiSAEj9vW5UQ2M1

Summary
Replaced the simple block-boundary text wrapping logic with a character-level wrapping algorithm that fills each line completely before moving to the next, even if it means breaking in the middle of an info block. This eliminates wasted space at the end of lines while properly handling ANSI color codes and emoji.
Key Changes
removeAnsiCodes()withwrapAnsiText(): The new function wraps text to a maximum visible width while intelligently handling ANSI escape sequences and emoji surrogate pairsImplementation Details
wrapAnsiText()function tracks the active ANSI color state and reapplies it when wrapping to a new line (unless a reset sequence was encountered)\x1b[and reading until the trailingmcharacterhttps://claude.ai/code/session_01PTMmeo1oiSAEj9vW5UQ2M1
