Fix incorrect boolean logic in automata DOT file format validation that allowed malformed files to pass undetected. The previous implementation used a logical AND operator where OR was required, causing the validation to only reject files when both the first token was not "digraph" AND the second token was not "state_automaton". This meant a file starting with "digraph" but having an incorrect second token would incorrectly pass validation. The corrected logic properly rejects DOT files where either the first token is not "digraph" or the second token is not "state_automaton", ensuring that only properly formatted automaton definition files are accepted for processing. Without this fix, invalid DOT files could cause downstream parsing failures or generate incorrect C code for runtime verification monitors.
