The counterfactual analysis now considers all hosts in OrderedHosts (not just the top-N) when simulating weigher removal. This prevents false claims where a host outside the top-N would actually become #1.

The scheduling pipeline's human-readable explanation previously only described which filter steps removed which hosts. Operators had no insight into why the weighing stage ranked hosts the way it did, especially when negative multipliers are involved. This adds a weighing explainer that recovers per-weigher multipliers via least-squares on the normal equations, performs counterfactual analysis to identify pivotal weighers whose removal would change the #1 host, and decomposes pairwise score gaps to surface the leading contributor and any opposing weighers. The result is appended to the existing generateExplanation output so operators can see actionable detail about ranking causality without any additional API surface.
