[BUG] Long text output truncated/cut off at terminal edge on macOS

Description

Long lines in Claude Code output are cut off at the right edge of the terminal instead of wrapping. Text after the cutoff point is lost — it's not accessible by scrolling horizontally. This makes it difficult to read longer output like recommendations or explanations, requiring the user to ask Claude to repeat the output in shorter lines. I think it has to do with the select, i.e. text above the select gets cut off.

Steps to reproduce

1. Run a command/prompt that produces long paragraph-style output (e.g., a recommendation or explanation that exceeds the terminal width) with a select
2. Observe that the text is cut off above the select
3. The truncated text is not visible — no horizontal scroll, no wrapping

Expected behavior

Long lines should wrap to the next line within the terminal, so all text is visible.

Actual behavior

Text is truncated at the terminal width boundary. The remainder of the line is lost.
