⚡ Bolt: [performance improvement] Optimize cache derivation with zip_with

[anchapin]

💡 What: Optimized ThermalModel::update_optimization_cache by replacing multiple chained VectorField .clone() math operations with unified .zip_with closures.
🎯 Why: Calculating physical thermal constants created multiple intermediate Vec allocations due to chained expressions A.clone() + B.clone() + C.clone(). This places unnecessary allocation pressure on the memory allocator.
📊 Impact: Reduces dynamic memory allocation calls inside update_optimization_cache during model setup and configuration loops.
🔬 Measurement: The engine_bench successfully executed and cargo checks passed with correct metrics.
