        };

-        // Check for duplicate token before creating hook
-        const hooksDir = path.join(basedir, 'hooks');


Only minor concern is that if an existing workspace(from before this version) has hook files, a duplicate token can be created once because the constraint file is missing?

We limit backwards compat in world-local to only ensure old runs can continue running, and can be viewed in o11y, so I think this is fine
