4/// Configurable weights for the scoring algorithm.
5///
6/// These weights determine the relative importance of different metrics
7/// when calculating a node's performance score. All weights should sum to 1.0.
8///
9/// # Examples
10///
11/// ```ignore
12/// // Prioritize response time and success rate equally
13/// let balanced_weights = ScoringWeights {
14///     latency: 0.4,
15///     success: 0.4,
16///     load: 0.2,
17/// };
18///
19/// // Prioritize low latency above all else
20/// let latency_focused = ScoringWeights {
21///     latency: 0.7,
22///     success: 0.2,
23///     load: 0.1,
24/// };
