/**
 * Capability gates and per-feature settings metadata, barrel exports and factory.
 *
 * Surfaces render FEATURE_SETTINGS: every platform capability as a first-class
 * domain setting (enablement key, option shapes, real descriptions). The gate
 * manager underneath is internal plumbing whose state derives from those same
 * settings keys; it also carries the emergency kill switch.
 *
 * Usage:
 * ```ts
 * import { createFeatureFlagManager, deriveFeatureStates } from './feature-flags/index.js';
 * const gates = createFeatureFlagManager();
 * gates.loadFromConfig({ flags: deriveFeatureStates(configManager) });
 *
 * // Check before using a gated subsystem
 * if (gates.isEnabled('exec-sandbox')) {
 *   // per-command sandbox is active
 * }
 *
 * // Emergency kill
 * gates.kill('exec-sandbox', 'Crash loop detected in production');
 * ```
