[Content] 推荐 codex-agents-local 支持了 AGENTS.local.md

### 想新增什么内容

AGENTS.md 在一个多人协作的场景下无法把一些自己私有的风格不好管理。
缺少 CLAUDE.local.md 这样的机制。

所以我之前做了 codex-agents-local 就是为了解决这个场景，感觉是可以分享给大家。

### 内容类型

团队实践

### 参考资料

_No response_

Start by locating the guide’s existing “团队实践” content and review how it currently explains AGENTS.md and related local instruction files. Read the linked codex-agents-local project, then add a focused recommendation describing the private-team-style use case and reference; done means the new content is placed consistently with the guide’s structure.
