Import Optimization

The codebase has been refactored to use more specific ES6 named imports instead of default module imports, reducing the amount of code loaded at runtime. This is an internal optimization with no functional impact on CLI behavior or features.

Technical details:

• Replaced import YJQ from "stream" with import { PassThrough as Jn5 } from "stream" at line 442149
• Replaced import oAQ from "node:process" with import { cwd as fNA } from "node:process" at line 361348
• The Transform class continues to be imported from stream (via YJQ.Transform at line 337901)
• The PassThrough class usage at line 442326 now uses the named import Jn5
• The cwd function usage at lines 361467 and 361469 now uses the named import fNA

Impact: None. This is purely an internal refactoring that improves code organization and potentially reduces memory footprint, but does not change any CLI functionality, commands, flags, or user-facing behavior.
