perf(build): use node:fs for cache checks

[43081j]

This switches from globby/cpy/etc to using the built-in node:fs functions.

We can use fs.cp to recursively copy, and fs.readdir to recursively read, so we no longer need dependencies to do this.

📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes
  • Improved cache file copying and detection for more reliable handling of nested directories.
  • Excluded junk files and directories during cache operations.
  • Preserved existing files when copying cached content.

Walkthrough

Updated cache filesystem utilities to use Node node:* imports, direct recursive fs.cp copying with junk filtering, and recursive fs.readdir checks for non-directory, non-junk entries. Removed the adjacent cpy and globby dependency entries from the package manifest.

- Around line 19-29: Update the cache copy implementation around the fs.cp call
so junk files are excluded without preventing traversal of directories or their
non-junk descendants. Remove the current filter-based behavior and pre-filter
entries or use a custom recursive walk, preserving recursive copying and the
existing destination options.
