fix(ci): remove redundant pnpm install from test-setup-script

The setup-and-install action already runs pnpm install --frozen-lockfile,
so running it again in test-setup-script is redundant and may cause issues
with the build output.

Simplified test-setup-script to:
- Clean dist/ and .vite cache with del-cli
- Build the CLI

This should resolve remaining 'Cannot find module dist/cli.js' errors
by ensuring the build output is not affected by a second install.
