⚡ Bolt: Remove LINQ .Sum() allocations in NetworkSimulationEngine

[google-labs-jules]

💡 What: Replaced LINQ .Sum() method calls with standard foreach loops in the AnalyzeContextResults method of NetworkSimulationEngine.cs.

🎯 Why: To reduce delegate and enumerator allocations. In hot paths, eliminating these allocations reduces garbage collection pressure, improving the execution speed of the simulation engine.

📊 Impact: Reduces heap allocations during context result processing by completely eliminating the delegate closure allocations per call to .Sum().

🔬 Measurement: The change was verified by running the existing unit test suite, and all tests passed, confirming no regression in functionality. Measured via code inspection that delegates are no longer generated for these aggregations.
