This pull request introduces a new method, Automaton.any_match(string), to provide a high-performance interface for checking if any keyword exists within a given string.
Currently, the most direct way to perform an existence check is next(A.iter(text), None) is not None. While functional, this pattern incurs overhead from the creation and state management of a Python-level iterator object. For high-throughput applications where only the presence of a match is needed, this overhead can be a bottleneck.
The any_match() method is a stateless, C-level function that implements a true early-exit search. It avoids Python object allocation for iterators or results, returning a singleton Py_True or Py_False. This provides a significant performance gain, especially in scenarios where matches are found early in the input text.
