feat: support standalone mode with @pnpm/exe bootstrap

Browse Source 
- When standalone=true, bootstrap with @pnpm/exe via npm ci
- When standalone=false, bootstrap with pnpm via npm ci
- Both use pnpm self-update to reach the target version
- Remove --ignore-scripts from npm ci so @pnpm/exe install scripts run
- Add standalone test back to CI
