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.
