tui2 backticks wrap

Can we make the wrap / no-wrap behavior configurable for tui2 copy implemention?

For example,

<img width="1866" height="88" alt="Image" src="https://github.com/user-attachments/assets/8d958910-b0bd-4bb8-a5fd-b16b1c30a60c" />

is copied as

````

rg -n -C 3 'backticks|inline code|line_to_markdown|span_is_inline_code|out.push_str\\(\"```\"\\)' codex-rs/tui2/src/transcript_copy.rs | sed -n '1,260p'

````

So if you want to use the command in a terminal, you need to manually remove the wrapping
