Copying text from CLI in iTerm2 inserts hard line breaks at terminal wrap boundaries

Summary

Selecting and copying Claude Code output from iTerm2 produces clipboard text with hard newlines wherever the terminal soft-wrapped the line for display. Pasting into a chat surface, doc, or editor requires manually re-flowing the text into paragraphs.

Environment

• Terminal: iTerm2
• OS: macOS (Darwin 25.4.0)
• Claude Code version: 2.1.132

Expected

Clipboard preserves the logical paragraph structure of the rendered output — soft wraps introduced for terminal width should not become hard newlines.

Actual

Every visual wrap point becomes a \n in the clipboard.
