OBJ_REGISTRY back to summary

OBJ_REGISTRY	back to summary
private static final ThreadLocal<Set<Object>> OBJ_REGISTRY Thread-local registry for cycle detection during `appendInternal`. Using `ThreadLocal` ensures thread safety without synchronization: each thread gets its own independent `Set`, so concurrent calls to `toString()` on different threads cannot interfere with each other. The set is backed by an `IdentityHashMap` so that membership checks use reference equality (`==`) instead of `equals`/`hashCode`. This is required because `hashCode()` on a self-referencing collection (e.g. `list.add(list)`) would itself cause a `StackOverflowError`.
