Add cases where a flipped decision changes the outcome: successful fleet and hint reads whose rows are missing or foreign, a node group with two Auto Scaling groups, trailing JSON after a valid value, terminated versus running instances, unknown quota codes with and without a name, the incomplete-observation count, every edge of the public token alphabet, and each family-to-kind pair of the public counts. EC2 hint reads must request managed resources; other reads must not. Each surviving mutant listed in the issue is killed by one of these cases (verified by applying each mutation locally).

Why
The EKS inventory check decides whether a paid trial cluster left anything behind. Mutation testing showed that several of its decisions could be flipped without any test noticing, including checks that a successful read really returned the resources that were asked for.
What
Adds tests where each listed decision changes the outcome, so flipping any of them now fails a test. Behaviour is unchanged; only tests are added.
