Can't build SPA with whitespace in path

[InfiiiinitY]

Describe the bug

Building a slidev presentation as an SPA using bun run build fails if the path or folder name contains whitespace.

Example path: C:\Users\z0187681\IT-Stuff\Visual Studio Code\Presi-Abschlussprojekt

Building leads to the following error:

$ slidev build

Minimal reproduction

Steps to reproduce the behavior:

1. Create a Slidev presentation with bun create slidev, preferably in a path without whitespace
2. Choose test slidev as the project name
3. Keep test-slidev as the package name
4. Notice that running bun run dev works fine
5. Try building with bun run build

Trying the same thing with test-slidev as project name leads to a successful build.

Environment

• Slidev version: 51.8.1
• Browser: Microsoft Edge / Zen (Firefox)
• OS: Windows 11

I'm not sure if this is a Slidev or a Vite problem. I just ran into it when trying to build my presentation and couldn't find any information about that problem.
