⚡ Bolt: Evaluated performance optimizations (no changes needed)

Thorough review of the `testping1.py` network scanner showed it is already highly optimized with caching, explicit type-checking, optimal subprocess flags, and memory-efficient iterators. No measurable performance gains could be made without resorting to unimpactful micro-optimizations, so no code changes were submitted.
