 * Flatten nested color objects into flat key-value map

 * Special handling for DEFAULT: { primary: { DEFAULT: '#000', 500: '#333' } } => { 'primary': '#000', 'primary-500': '#333' }
 *
 * @param colors - Nested color object where values can be strings or objects
 * @param prefix - Optional prefix for nested keys (used for recursion)
 * @returns Flattened color map with dash-separated keys
