…eeMap` `Map.of(..)` does not preserve iteration order, so converting order-sensitive maps silently drops their ordering contract.

Map.of(..)makes no iteration-order guarantee, so converting an order-sensitiveLinkedHashMap(orTreeMap) silently drops the ordering contract callers rely on. TheNEW_HASH_MAPmatcher usedmatchOverrides=trueto catch thenew HashMap<>() {{...}}anonymous-subclass idiom, which also caused it to match non-anonymousHashMapsubclasses. Added aTypeUtils.isOfClassTypecheck on the declared class so onlyjava.util.HashMapis rewritten, with regression tests forLinkedHashMapandTreeMap.
