STAT pruning + OS/2 fsSelection update + name table hardening. The instancer pipeline now prunes STAT AxisValueRecords whose AxisIndex no longer points at a live fvar axis (eliminates dead OS-menu entries) and updates the OS/2 fsSelection mask + name table records (nameID 2 Subfamily → 'Regular', nameID 3 Unique ID regenerated from head.fontRevision) so restricted files no longer collide with the source font in OS font caches.
