jvm-langs: intellij platform CLEAN; kotlin/scala3 defects already committed

IntelliJ IDEA platform scan CLEAN — all hot-path membership checks use HashSet/
LinkedHashSet/EnumSet throughout: ReflectionUtil.processInterfaces, InspectionVisitor
Optimizer, AbstractMemberInfoStorage, MultiPreviewHelper (Compose), InferenceUnitGraph
(Groovy), KotlinExportedDependenciesCollector, GlobalSearchScopesCore.myDirectories.
No O(N²) list-as-visited patterns found.

kotlin-0001/0002 and scala3-0001 patch docs already landed in 068ebbd29f.

-# traefik — CWE-407 Scan Result: CLEAN
-
-Scanned 2026-03-29.
-
-## Findings
-
-All `slices.Contains` / `slices.ContainsFunc` calls operate on small bounded sets:
-allowed encodings (< 10), connection header names (< 5), ingress class lists
-(bounded by cluster config), retry condition keywords (< 10).
-
-No custom slice-contains helpers in hot paths. No O(N²) traversal patterns found
-in router, middleware, or provider code.
-
-**Verdict: CLEAN** — no CWE-407 defects warranting a patch.
