fix(ci): replace rm -rf with cross-platform del-cli command

The rm -rf command fails on Windows PowerShell, causing test-setup-script
to fail and preventing dist/cli.js from being built. This resulted in
'Cannot find module dist/cli.js' errors across all Windows test runs.

Changed from:
  rm -rf packages/cli/node_modules/.vite packages/cli/dist

To:
  pnpm exec del-cli packages/cli/node_modules/.vite packages/cli/dist

This uses the del-cli package which works consistently across all platforms
(Windows, macOS, Linux).
