Introduce composable Metric (per-run scalar) and Aggregation (across-run reducer) types that compose into KPIs, aligning with the simulation glossary hierarchy. KPI now accepts either legacy fn or metric+aggregation pair. Built-in metrics: final_value, trajectory_mean, max_value, min_value Built-in aggregations: mean, std, percentile, probability_above/below Evaluator populates per-run distributions for metric-based KPIs. Closes #118
Overview, getting started guide, concept hierarchy (Metric/Aggregation/KPI), parameter spaces reference, optimizer guide, and API reference pages. Adds psuu section to mkdocs nav and landing page package table.
