The hook scripts used absolute imports like `from hookify.core.config_loader`
but when installed, the plugin lives in a cache directory with a hash name,
not in a directory named `hookify/`. Python couldn't resolve the package.
Changed to local imports (`from core.X`) which work because PLUGIN_ROOT
is added to sys.path. Also simplified the sys.path setup.
