docs(codex): README and the skill's blocked-worker recipe know codex blocks

The README (both languages) still said only claude and deepseek sessions
emit `blocked` and that codex accepts only idle, working and exit, and the
skill's Flow 5 called `blocked` claude-mode only. Codex now raises it from
its screen-read dialogs; the recipe says to watch it with
`until=blocked,exit` (codex has no `stop`) and to answer in the terminal.
The plugin mirror is regenerated with scripts/sync-plugin.mjs.

 4. **Response envelope.** Most endpoints return `{ "success": true, "data": … }` (errors: `{ "success": false, "error", "errorCode" }`). A few legacy GETs return bare bodies — **handle both** (`body.data ?? body`).
 5. **`/api/v1/*`** is a stable alias of `/api/*`.
 6. **Wait instead of polling, and don't treat a timeout as an error.** The wait endpoints answer with HTTP `200` and `wait.timedOut: true` when nothing happened in time, so loop over short waits (60s is the default) rather than issuing one long call, because tunnels cut idle connections. `wait.timeoutMs` tells you the timeout the server actually applied after clamping (600s ceiling).
-7. **Only `claude` and `deepseek` sessions emit `stop` and `blocked`.** Those two come from hooks (Claude Code's own, and the DeepSeek Harness status bridge); `shell` and the other external CLIs (opencode/codex/gemini/antigravity/pi/grok/omp) accept only `idle`, `working` and `exit`. Asking for `stop` explicitly on those is a `400`; omitting `until` is always safe. ⚠️ On a `shell` session `idle` fires **once**, at startup, and never again, so send-and-wait there can only time out; synchronize hook-less sessions with a `wait-output` marker.
+7. **Only `claude` and `deepseek` sessions emit `stop`; `codex` emits `blocked` too.** Those come from hooks (Claude Code's own, and the DeepSeek Harness status bridge), except codex's `blocked`, which Codeman reads off its screen while an approval, question or trust dialog is up (answer it in the terminal). `shell` and the other external CLIs (opencode/gemini/antigravity/pi/grok/omp) accept only `idle`, `working` and `exit`, and codex adds `blocked`. Asking for `stop` explicitly on those is a `400`; omitting `until` is always safe. ⚠️ On a `shell` session `idle` fires **once**, at startup, and never again, so send-and-wait there can only time out; synchronize hook-less sessions with a `wait-output` marker.
 8. **Nothing reports "ready", so wait for it explicitly.** A new session answers `{"signal":"exit","immediate":true}` (that means *not started*, not *crashed*) until its PID exists, and a `claude` worker in a fresh case then sits on the CLI's trust dialog. Prompt it there and the wait resolves on `idle` in ~2s looking exactly like a finished turn, while the text sits stuck in the dialog. Recipe 2b below is the sequence that avoids it.

 4. **响应信封。** 多数端点返回 `{ "success": true, "data": … }`（错误：`{ "success": false, "error", "errorCode" }`）。少数遗留 GET 返回裸响应体 —— **两种都要处理**（`body.data ?? body`）。
 5. **`/api/v1/*`** 是 `/api/*` 的稳定别名。
 6. **用等待代替轮询，别把超时当成错误。** 等待类端点在没等到事情发生时也以 HTTP `200` 加 `wait.timedOut: true` 应答，所以要循环调用短等待（默认 60 秒），而不是发一个超长的调用：隧道会掐断空闲连接。`wait.timeoutMs` 告诉你服务端钳制之后真正采用的超时（上限 600 秒）。
-7. **只有 `claude` 与 `deepseek` 会话会发出 `stop` 与 `blocked`。** 这两个来自 hook（Claude Code 自己的，以及 DeepSeek Harness 的状态桥接）；`shell` 与其他外部 CLI（opencode/codex/gemini/antigravity/pi/grok/omp）只接受 `idle`、`working` 与 `exit`。在这些模式上显式索要 `stop` 会得到 `400`；不传 `until` 则永远安全。⚠️ `shell` 会话的 `idle` 只在启动时触发**一次**，此后再也不会，所以在那里用「发送并等待」只能等到超时：没有 hook 的会话请用 `wait-output` 标记来同步。
+7. **只有 `claude` 与 `deepseek` 会话会发出 `stop`；`codex` 还会发出 `blocked`。** 它们来自 hook（Claude Code 自己的，以及 DeepSeek Harness 的状态桥接），codex 的 `blocked` 除外：批准、提问或信任对话框出现时，Codeman 从它的屏幕上读出这个信号（请在终端里回答）。`shell` 与其他外部 CLI（opencode/gemini/antigravity/pi/grok/omp）只接受 `idle`、`working` 与 `exit`，codex 另外接受 `blocked`。在这些模式上显式索要 `stop` 会得到 `400`；不传 `until` 则永远安全。⚠️ `shell` 会话的 `idle` 只在启动时触发**一次**，此后再也不会，所以在那里用「发送并等待」只能等到超时：没有 hook 的会话请用 `wait-output` 标记来同步。
 8. **没有任何东西会报告「就绪」，得自己显式等。** 新会话在 PID 出现之前一律回答 `{"signal":"exit","immediate":true}`（意思是*还没启动*，不是*崩了*），而全新 case 里的 `claude` 工作会话接着会停在 CLI 的信任对话框上。此时给它发提示，等待会在约 2 秒后因 `idle` 解除，看上去和一个跑完的回合一模一样，而文本其实卡在对话框里。下面的配方 2b 就是避开它的顺序。
