Please rethink how readVaultTokenFromFileSystem method works.
It relying on UNIX console commands which will fail on Windows machine.
If ENV HOME is not available read from .env and do not overcomplicate the logic.

I do suggest to use native PHP functions to read it.

It's based on previous develop where we have the other vault story in place. Now it's been reverted and thus the merge conflict. I think i will wait for 2.4.3 tag cut.
