peazip-sources/dev/metadarkstyle/ should not be deleted.
peazip-soirces should replicate the content of the standalone sources package, which needs metadarkstyle in order to successfully compile for Windows systems.

But I made autodownload from lazarus package

That is OK for the automated procedure, but at the same time I need to preserve the availability of metadarkstyle sources for manual building.

The subdirectory, and the standalone source package, contains a local copy of metadarkstyle, which is tested for working correctly with the current version of the source code of the application.

Ideally the local version should work as fallback if the online version of the package on Lazarus repository gets for any reason unavailable, corrupted by a supply chain attack, abandoned, or if an update makes it temporarily not fully working along the rest of the codebase.

If it is OK for you, I can merge the pull request, and then restore the metadarkstyle subdirectory in peazip-sources.
