⚡ Bolt: [performance improvement]

[google-labs-jules]

💡 What: Replaced multiple LINQ .ToDictionary() allocations with manual, pre-sized Dictionary initialization and foreach loops in ToRoutingContext within TemporalNetworkSimulationEngine.cs.

🎯 Why: The ToRoutingContext method is on a hot path during temporal simulation runs. The repeated .ToDictionary() calls for Supply, SupplyUnitCosts, and Demand were creating significant memory allocation bottlenecks due to enumerator and delegate generation overhead, as well as dynamic dictionary resizing.

📊 Impact: Entirely eliminates LINQ allocation overhead and garbage collection pressure for these dictionary conversions, improving hot path execution speed.

🔬 Measurement: Verify by running network simulations with temporal properties enabled and profiling memory allocations; delegate and enumerator allocations in this scope should be zero.
