Module Import Optimization

Refined Node.js module imports to be more specific, importing only the required functions rather than entire modules. This change reduces memory footprint and improves load times.

Technical details:

  • Changed from import AKQ from "stream" to import { PassThrough as ht5 } from "stream" at line 445281
  • Changed from import i9Q from "node:process" to import { cwd as y7A } from "node:process" at line 357186

These optimizations have no impact on CLI behavior or available features—they simply make the code more efficient internally.
