💡 What:
Replaced the linear scan in
Scanner.GetSignaturewith a map-based lookup (sigMap map[string]int).🎯 Why:
The previous implementation iterated through the entire signature list to find a signature by ID, which is O(N). With thousands of signatures, this becomes a performance bottleneck. The optimization reduces this to O(1).
