Import Statement Optimization#

This release refactors how Node.js built-in modules are imported throughout the codebase:

  • stream module: Changed from default import (import us from "stream") to named import (import { PassThrough as Xz8 } from "stream") at line 457820
  • node:child_process: Changed from default import (import cB0 from "node:child_process") to named imports (import { execSync as F7B, spawn as Lk6 } from "node:child_process") at line 276288
  • node:process: Changed from default import (import cNQ from "node:process") to named import (import { cwd as nUA } from "node:process") at line 70245

Technical details: These changes optimize the module loading by importing only the specific functions needed rather than entire module namespaces. The functionality remains identical - all three modules (stream, node:child_process, and node:process) are still used in exactly the same way, just with more precise imports.

User impact: None. This is purely an internal code quality improvement with no behavioral changes.
