Subject: [PATCH 1/3] fix: use directory-level unpack patterns to avoid
 minimatch length limit

When merging ASARs for universal builds, the unpack pattern was
constructed by listing every individual unpacked file path in a brace
expansion like `{file1,file2,...}`. For projects with many unpacked
files (e.g. auto-unpacked native modules), this pattern can exceed
minimatch's 64 KiB limit, causing a "pattern is too long" TypeError.

This change groups unpacked files by their top-level directory (e.g.
`node_modules/pkg` or `dist/main`) and uses `**` glob patterns instead.
This reduces thousands of entries to a handful of directory patterns
while preserving the same unpack behavior.

Fixes https://github.com/electron-userland/electron-builder/issues/7044
