chore(test): remove the regression test suite

Removed at the maintainer's request. The four tests covered the auto->tun
and ass->proxy preference migrations, secure SOCKS session generation, and
the patched Xray SOCKS authentication schema.

Note that nothing now guards the build-time patchers against schema drift;
their fail-closed anchors are the only remaining check.
