First public (pre-)release Wormhole

First release but marked as pre-release due to the imperfect nature of the distributables. Basically used to test Github Actions as no new features have been added as compared with the previous pre-release.

The binaries are distributed as compresses launcher/folder with dependencies in their native, default compression format.
