perf: loop variable hoisting in Minimizer

[Tugamer89]

What

Refactored the splitGroup method in Minimizer.java to hoist the invariant transitions == null check out of the loop over alphabetArray. Also implemented Arrays.fill to efficiently handle array population when transitions is null.

Why

This avoids repeatedly evaluating an invariant condition inside a loop, which adds up as alphabetArray length scales. Calling Arrays.fill simplifies the iteration and is highly optimized intrinsically. This helps speed up the compilation and minimal DFA calculation process.

Impact

Improves execution speed during DFA minimization, reducing CPU cycle waste when handling character targets. This optimization leads to better performance when evaluating large transition tables without significantly impacting code readability.

Measurement

The refactored code successfully passed the entire mvn clean test test suite and spotlessly formatted. Execution logs from manual bash validation matched expected output structure perfectly.
