`void init` defaults to pnpm on Windows without checking if it's installed

[ioNihal]

Describe the bug

Package manager available: npm only (no pnpm).

Expected behavior:
void init should detect which package manager is available on the system and use it, or explicitly ask the user which package manager to use during the interactive flow.
Actual behavior:
Vite+ defaults to pnpm and attempts to run pnpm install, which fails with a "pnpm not found" error if pnpm isn't installed. There is no fallback to npm and no prompt to choose a package manager.

Additional context:
Also encountered a secondary bug on Windows: at the end of void init (when run in an existing project), the Drizzle migration step fails with:
'C:\Program' is not recognized as an internal or external command
This appears to be a Windows path-with-spaces quoting issue in the migration runner.
What i did was, I chose no database, then on next step, when it prompted to setup a API route demo project, I chose Yes

Reproduction

No URL, tested on local

Steps to reproduce

Create a fresh empty directory
Run npm install -D void
Run npx void init in that empty directory
Select Vite+ as the toolchain
Complete the interactive prompts
