Notes

• All commands follow existing patterns (cookie strategy, browser-based XHR)
• Cookie expiry (code 7/37) handled consistently
• Write operations use UI automation where BOSS doesn't expose direct APIs

CI Note

The 4 failing unit-test jobs are pre-existing failures in main, unrelated to this PR:

• src/clis/xiaohongshu/creator-notes.test.ts — "prefers the creator analyze API and preserves note ids"
• src/clis/xiaohongshu/creator-note-detail.test.ts — "appends trend summary rows from hour/day series payloads"

Both are xiaohongshu (小红书) module tests. This PR only adds files under src/clis/boss/.

✅ build job passed
✅ e2e-headed passed
✅ audit passed

CI 说明

4 个失败的 unit-test 是 main 分支上已有的问题，与本 PR 无关：

• src/clis/xiaohongshu/creator-notes.test.ts — "prefers the creator analyze API and preserves note ids"
• src/clis/xiaohongshu/creator-note-detail.test.ts — "appends trend summary rows from hour/day series payloads"

都是小红书模块的测试用例。本 PR 只新增了 src/clis/boss/ 下的文件，未修改任何已有代码。

✅ build 通过
✅ e2e-headed 通过
✅ audit 通过
