This fixes an issue where fs.cp and fs.cpSync (when a filter is provided) correctly restore mtime and atime on copied files when preserveTimestamps: true is passed, but skip restoring them for directories. The fix applies the existing setDestTimestamps helper to directories, ensuring it is called after directory creation/copying but before any modes are restored (since restoring a read-only mode would prevent timestamp modification). Note: This fix covers fs.cp() (async, all cases) and fs.cpSync() when a filter is provided. The native fast path used by cpSync() without a filter (CpSyncCopyDir in src/node_file.cc) has the identical gap and is left for a separate follow-up contribution, since it requires native code changes and a different review path.

fs: preserve directory timestamps in cp
This fixes an issue where fs.cp and fs.cpSync (when a filter is
provided) correctly restore mtime and atime on copied files when
preserveTimestamps: true is passed, but skip restoring them for
directories.
The fix applies the existing setDestTimestamps helper to directories,
ensuring it is called after directory creation/copying but before any
modes are restored (since restoring a read-only mode would prevent
timestamp modification).
Note: This fix covers fs.cp() (async, all cases) and fs.cpSync()
when a filter is provided. The native fast path used by cpSync()
without a filter (CpSyncCopyDir in src/node_file.cc) has the
identical gap and is left for a separate follow-up contribution, since
it requires native code changes and a different review path.
