[Bug] ERR_TTY_INIT_FAILED on git bash (MINGW64)

[Divyansh Singh]

Environment

• OS: Windows
• Node Version: v22.0.0
• Package: @clack/prompts
• Package Version: v0.7.0

Describe the bug

https://github.com/natemoo-re/clack/blob/45ee73bf33b25f9a8c7e1bb6117ccc165478bf4d/packages/core/src/prompts/prompt.ts#L82

This line throws ERR_TTY_INIT_FAILED when used inside terminals like Git Bash, most likely because of the extra basedir stuff added by package managers in node_modules/.bin/*.

To Reproduce

You'll need a Windows machine (or VM, I'm using UTM on mac) with Git Bash installed. Then try running any project using clack. For example with VitePress:

mkdir foo
npm add -D vitepress
npx vitepress init

Or with Svelte:

npm create svelte@latest foo

Expected behavior

Work similar to other terminals or maybe a fallback strategy in case write stream can't be opened on stdin.
