Using standalone pnpm on windows is not possible #6503

When using standalone pnpm on windows, the pnpm commands open a separate process window.

This is particularly problematic for CI, where process goes missing and CI reports successful step without ever waiting for the response from that process.

pnpm version: 8.4.0

Code to reproduce the issue:

• Install standalone pnpm - npm i -g @pnpm/exe@latest
• Checkout any repo with pnpm-lock.yaml (e.g. git clone git@github.com:pnpm/pnpm.git)
• Run pnpm i --frozen-lockfile

Expected behavior:

• Standalone pnpm runs in the same process window from which it was called

Actual behavior:

• Notice how install process runs on a separate window and the original window reports process as done immediately

Additional information:

• node -v prints: Irrelevant since @pnpm/exe comes prebundled with node
• Windows, macOS, or Linux?: Windows
