v3.27.3

• dsh: GLM vision models keep their native sight behind gateways that spell versions with dashes (#126). The name check that keeps native vision models out of the (modlens vision) wrap only knew the dotted spelling (glm-5.3-flash, glm-4.6v). Gateways such as Raccoon serve the same models as sn-glm-5-3-flash and sn-glm-4-6v, so after adding the gateway prefix to families, a catalog that omits modalities would have handed a vision model a wrapper twin. Both spellings are now excluded, and the text-only sn-glm-5-3 still wraps. Default family matching stays prefix-only: a gateway namespace is opted in through families, as before.
