Refactor the DOT file parsing logic in automata.py to use Python's iterator-based patterns instead of manual cursor indexing. The previous implementation relied on while loops with explicit cursor management, which made the code prone to off-by-one errors and would crash on malformed input files containing empty lines. The new implementation uses enumerate and itertools.islice to iterate over lines, eliminating manual cursor tracking. Functions that search for specific markers now use for loops with early returns and explicit AutomataError exceptions for missing markers, rather than assuming the markers exist. Additional bounds checking ensures that split line arrays have sufficient elements before accessing specific indices, preventing IndexError exceptions on malformed DOT files. The matrix creation and event variable extraction methods now use functional patterns with map combined with itertools.islice, making the intent clearer while maintaining the same behavior. Minor improvements include using extend instead of append in a loop, adding empty file validation, and replacing enumerate with range where the enumerated value was unused.
