/**
 * @fileoverview Scope-owned fitness registries — the simulation pattern.
 *
 * Each `RunScope` owns its own check + recipe registries (D7 — tool
 * subscopes via module augmentation). The fitness tool's
 * `contributeScope` hook constructs fresh registries per CLI invocation
 * and attaches them to `scope.fitness.{checks,recipes}`. The module-level
 * singletons (`defaultRegistry` / `defaultRecipeRegistry`) are gone —
 * consumers read via `currentCheckRegistry()` / `currentRecipeRegistry()`,
 * which route through the scope-bound instances and throw outside a scope.
 *
 * Public API (mirrors simulation's `createScenarioRegistry` /
 * `currentScenarioRegistry`):
 *   - `createCheckRegistry()`   — factory used by `contributeScope`.
 *   - `createRecipeRegistry()`  — factory used by `contributeScope`.
 *   - `createFitnessLoadState()`— fresh `ensureChecksLoaded` lifecycle slot.
 *   - `currentCheckRegistry()`  — reads `scope.fitness.checks`; throws
 *                                 outside a scope / when the subscope is absent.
 *   - `currentRecipeRegistry()` — reads `scope.fitness.recipes`; same throws.
 *   - `currentFitnessLoadState()` — reads `scope.fitness.load`; same throws.
