BridgeMethodResolvercandidate selection for multi-level generic Kotlin suspend overrides.When both methods use the Kotlin suspend ABI, compare their logical Kotlin return types. All other methods retain the existing JVM return-type check, preserving covariant-return disambiguation.
Add regression coverage for both specialized and root bridges in a multi-level generic suspend hierarchy.
