/**
 * Configuration Path Utilities
 *
 * Centralized utilities for resolving Wave configuration file paths.
 * Supports both regular settings.json and local settings.local.json with proper priority.
 *
 * Priority system:
 * - User configs: ~/.wave/settings.json
 * - Local configs: {workdir}/.wave/settings.local.json > {workdir}/.wave/settings.json
 * - Project configs override user configs (existing behavior)
