 * @remarks
 * Uses direct tree walking to index elements with directive attributes,
 * then executes directives to produce the final HTML.
 * Directive attributes are preserved in output for client hydration.
 * Directives are processed in tree order (parents before children),
 * with priority used only for multiple directives on the same element.

 * @param state - The state object to use for expression evaluation
 * @param registry - The directive registry

 * @returns The rendered HTML string
 *
 * @example
 * ```ts
 * const registry = new Map();
 * registry.set('text', textDirective);
 *
 * const html = await render(
 *   '<span g-text="user.name"></span>',
 *   { user: { name: 'Alice' } },
