Pull request overview

This PR fixes an issue where parent directories were incorrectly marked as unpacked when packaging ASAR archives. The fix removes the automatic propagation of the unpacked flag to parent directories, allowing the electron/asar library to determine directory unpacked status automatically based on their contents.

Key Changes:

• Refactored the two-pass directory processing logic to first create parent directories with unpacked: false, then propagate the flag (though this second step appears to be unintentionally retained)
• Simplified the isUnpacked check to take additional parameters (file and stat) for more accurate unpacking decisions
• Refactored helper methods and code organization for better clarity

File	Description
packages/app-builder-lib/src/asar/asarUtil.ts	Refactored ASAR packaging logic to use a Map-based approach instead of arrays, changed how parent directories are marked as unpacked, and simplified various helper methods
test/snapshots/globTest.js.snap	Removed "unpacked": true flags from parent directories in multiple test cases, confirming that only files (not their parent directories) should be explicitly marked as unpacked
test/snapshots/HoistedNodeModuleTest.js.snap	Removed "unpacked": true flag from parent directory, consistent with other snapshot changes
.changeset/light-flies-count.md	Added changeset documenting the fix as a patch-level change
