fix: generic types now carry package prefix in schema names

shortenGenericName was building the container name from m[1] (raw type
name, no package info), causing e.g. ResponseTodoList instead of
ModelResponseTodoList. Fix by extracting the container portion from
defaultDefName, which already has the package prefix applied and
StripDefinitionNamePrefix run — making generic schema names consistent
with non-generic structs.
