Module Import Optimization

What changed: Switched from default imports to named imports for Node.js built-in modules Changes:

• import crypto from "crypto" → import { createHash, randomBytes } from "crypto"
• import stream from "stream" → import { PassThrough } from "stream"
• import process from "node:process" → import { cwd } from "node:process"

Impact: Slightly improved tree-shaking and bundle optimization
