1.46.2
(fix): Fix double-pointer types for nullable $ref alias fields in v2 GoTypeMapper and DynamicTypeMapper,
consistent with the v1 fix in model.go.
1.46.1
(fix): Fix double-pointer types generated for nullable date fields that reference
shared component schemas via $ref. When a nullable type alias (e.g.
type Iso8601DateNullable = *time.Time) was used as a field type, the
generator incorrectly produced *Iso8601DateNullable (effectively
**time.Time), causing Go compilation errors. The generator now detects
aliases that already resolve to pointer types and avoids wrapping them in
an additional pointer.
