Subject: [PATCH] feat(dispose): add debug checks for double disposal

Added debug-only checks in Dispose methods of HashMapHelper, UnTypedArray, and UnsafeArray to log a message (with optional stack trace) if Dispose is called on an uninitialized or already disposed instance, unless the buffer is null. Incremented assembly version to 1.6.6.
