v3.3.9

• TreeReferenceMap:
  • Rollback: avoid WeakReference issues with WASM on Android/Chrome:
    • Replaced internal _map from WeakKeyMap<K, V> to standard Map<K, V>.
    • Updated all _map method calls from containsKeyNoPurge to standard containsKey.
    • Adjusted put, get, addAll, containsKey, and containsValue methods to work with the new _map type.
    • Removed usage of weak key map features and related purging logic tied to it.
