[Bug] Leading spaces are trimmed in prompts

[gBasil]

Environment

• OS: macOS
• Node Version: v24.0.1
• Package: @clack/core
• Package Version: v0.5.0

Describe the bug
Clack seems to trim leading blank spaces in each line when displayed with render (at least in GroupMultiSelectPrompt, though I presume this would be a larger issue).

To Reproduce
https://stackblitz.com/edit/node-kgstubgf?file=index.mjs

Steps to reproduce the behavior:

• Run node index.mjs in the StackBlitz project above.

Expected behavior
The blank spaces at the beginning of the line should not be removed

Additional Information
When a non-space character is put at the start, the spaces after it are properly rendered. Also, other unicode space characters seem to work (i.e. zero-width spaces (\u200B)), just not the one placed by the space bar.

this is likely already fixed in the 1.x branch

can you try out @clack/prompts@alpha?

it doesn't seem likely this will be backported to 0.x though as its a large rework
