fix: 补充 ClientConfig 接口和 clientConfig() 方法

- auth-cli.ts 加载时自动生成 SKILL_SESSION_ID（格式: skill-YYYYMMDD-HHMMSS-xxxx）
- 优先级: 已有 SKILL_SESSION_ID env > 自动生成
- 所有 import 此文件的 skill 自动获得 session 追踪

+ * Thin CLI wrapper for auth-runtime.
+ *
+ * Copy this file into your skill's src/ directory. It calls the
+ * `auth-rt` binary (a standalone Go executable), so the skill has
+ * zero npm/runtime dependency on auth-runtime.
+ *
+ * Prerequisites:
+ *   `auth-rt` must be in PATH or at ~/.local/bin/auth-rt
+ *   (install.sh handles this automatically)
+ *
+ * Usage:
+ *   import { createSkillClient } from './auth-cli.ts';
+ *   const client = createSkillClient();
+ *   const res = await client.post('/ecom/tasks/scrape', { url: '...' });
