CancelledException class

Exception thrown when a query operation is cancelled.

This exception is caught silently by the query system and does not propagate to error handlers or update query state to error.

Example:

queryFn: (token) async {
  token.throwIfCancelled();
  final result = await fetchData();
  token.throwIfCancelled();
  return result;
}
