Overriding the breaking release here, making it non-breaking instead.

• feat!: Extend LowerTypes pass to linearize by inserting copy/discard #2018 was marked as non-breaking, but it only affected non-published code
• feat: Represent order edges in hugr-model as metadata. #2027 added a variant to the exhaustive hugr_core::import::ImportError enum, but the module is behind an unstable feature flag.
