Use sorted key arrays when serializing contexts to avoid allocating an ArrayList for each serialization. This preserves deterministic key ordering while keeping the snapshot representation smaller. Co-Authored-By: Claude <noreply@anthropic.com>

📜 Description
Uses sorted
String[]key snapshots when serializingContextsandMonitorContexts.This replaces
Collections.list(keys())plusCollections.sort()withkeySet().toArray(...)plusArrays.sort(...).💡 Motivation and Context
Context serialization needs deterministic alphabetical key ordering, but the previous implementation allocated an
ArrayListwrapper for each serialization. A plain key array preserves the same ordering behavior while avoiding the extra list allocation.💚 How did you test it?
