Conversation
The LINQ query on `context.Demand` was being re-evaluated for every iteration of the outer producer loop. This led to O(N*M) LINQ evaluations and allocations. By hoisting both supply and demand queries into pre-materialized lists, we reduce the complexity to O(N+M) per call, significantly reducing GC pressure and CPU overhead in the simulation engine's hot path.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

💡 What: Hoisted the LINQ queries for
context.Supplyandcontext.Demandinto pre-calculated lists before entering the nested loops inBuildCandidateRoutes.🎯 Why: The$O(N \times M)$ allocations and CPU cycles for filtering and projection.
context.Demandquery was being re-evaluated for every producer node, resulting in redundant📊 Impact: Reduces LINQ evaluation and allocation complexity from$O(N \times M)$ to $O(N + M)$ per
BuildCandidateRoutesinvocation. This significantly lowers GC pressure and execution time in the simulation engine's bottleneck, which is called repeatedly during global capacity bidding.🔬 Measurement: Full benchmarks were impractical due to 400s timeouts in the current CI environment for NuGet restore and build processes. The improvement is justified by the reduction in redundant work within a nested loop on a hot execution path.
