That's on purpose, and required, for a variety of reasons. First would be that it cannot be put together into a single executable as it is composed of multiple, separate components, that each rely on a specific structure of the file system being present. This is not something I can control. Second, Portacle is made in such a way that all three platforms can be combined together into a single directory so that it can be run on any system as one, which mandates a shared folder structure. Third, in order to be self-contained, the Portacle installation directory must contain its own configuration and project directories. It makes no sense to allow you to move the executable outside of this, and it would make no sense to put those directories within the .app on, say, mac.
