* docs(devapp): add image-upload recipe + "discovering commands" to dingtalk-dev skill

The dingtalk-dev skill could set an app/robot icon via --icon-media-id but
never documented where a mediaId comes from: the dev command set has no
upload command, so a mediaId must be fetched from DingTalk's OpenAPI. Agents
had to guess the flow. The per-resource refs also lacked a uniform pointer to
self-discover commands and params, so they leaned on memory instead of --help
/ schema.

recipes.md: new "上传图片拿 mediaId" recipe — credentials get -> gettoken ->
OpenAPI /media/upload (multipart field `media`, type=image) -> robot config /
app update --icon-media-id -> read back. Includes a curl example and notes the
token TTL (~7200s, rate-limited) and a square-icon hint.

references/*.md: append a Chinese "发现命令" block to each of the 10 product
refs (app, credentials, webapp, permission, member, security, robot, version,
event, connect). Each block shows that group's own `--help` plus
`dws schema dev.app.<group>.<method>` (connect uses `dws schema dev.connect`),
mirroring SKILL.md's MUST DO.

Verified end-to-end on a real app (unifiedAppId via dws dev): uploaded a PNG
through /media/upload, set the robot icon with the returned mediaId, and
`robot get` reflected the new iconMediaId with robotStatus=ONLINE. All 10
`--help` targets and the 9 `dws schema dev.app.*` paths + `dws schema
dev.connect` resolve.

* docs(changelog): note dingtalk-dev mediaId recipe + command discovery (#508)

# 事件订阅
> 把应用关心的事件推到回调地址;见 SKILL.md 概念地图。
`dws dev app event list/subscribe/unsubscribe`,按 `--unified-app-id` 定位,订阅/退订用 `--event-codes`(逗号分隔,一次多个)。参数查 `dws schema dev.app.event.<method>`。
规则:
- 写操作先 `--dry-run` 预览,确认后 `--yes`。
- 一次可订阅多个事件码,共用同一回调。
- **事件码定位优先用 `event list --keyword <关键词>` 搜索**(按事件码或事件名称模糊匹配);只有用户明确要「全部事件」时才不带 `--keyword` 翻全量。
- 可订阅的事件码通过 `event list` 查询:返回 `events[]` 列出 `eventCode/eventName/subscribed`,不用查文档。
- 退订前先 `event list` 确认当前订阅,避免退不存在的。
- 翻全量时用 `--cursor/--page-size` 逐页处理;返回 `events/hasMore/nextCursor/pageSize`,翻页继续传 `nextCursor`。
- 批量或全量订阅前,先把候选 `eventCode` 列给用户确认,再 `--dry-run` → `--yes`。
- 返回看 `events[].subscribed` 和 `pushType=STREAM`(事件走 Stream 长连推送;connect 与事件订阅的关系见下方「Stream 长连」)。
- `subscribe/unsubscribe` 的 `--event-codes` 必填,返回 `success/operation/unifiedAppId/eventCodes/needsPublish/versionRequiredAction`;失败时补 `errorCode/errorMsg/reason/retryable/action`。
- 如果服务端返回 `errorCode=STREAM_NOT_CONNECTED`、`reason=STREAM_NOT_CONNECTED`、`retryable=false`、`action=run connect`,先执行 `dev connect` 建联,再重试订阅。
## Stream 长连:connect 与事件订阅的关系
钉钉一个应用就一条 Stream 长连(WebSocket),上面同时承载机器人消息、事件、卡片回调等多种 topic。connect 和 event 在这条长连上分工不同:
- `dev connect`:用应用凭证把这条长连建起来并保活,但只注册了机器人消息处理(收 @机器人 → 转发本地 agent),**不消费事件**。
- `event subscribe/unsubscribe`:只是**配置**操作(配应用订阅哪些事件码),自己不建长连、不收事件;服务端要求应用的 Stream 长连已在线,否则返回 `STREAM_NOT_CONNECTED`。
- 两者唯一关联:先 `dev connect` 把长连建在线,`event subscribe` 才能成功——connect 负责「让长连在线」,subscribe 负责「配置订阅」。
- 当前限制:connect 的长连不处理事件,dws 也没有「收/消费事件」的运行时命令,event 只到「配置订阅」为止。订阅成功后真正的事件推送 dws 暂不消费——要消费得用注册了事件 handler 的 SDK 自接(事件结构走 `dev doc search` 查)。
## Stream 长连怎么建的
`dev connect` 内部用 dingtalk-stream-sdk-go,凭 `clientId/clientSecret` 建一条 WebSocket 长连并保活——底层网关握手、ticket、加解密都由 SDK 封装,agent 跑 `dev connect` 即可,不用碰这些。
dws 当前只消费机器人消息、不消费事件。要自己写事件消费程序补这个 gap 时,SDK 用法以官方文档为准(走 `dev doc search`,或看 github.com/open-dingtalk/dingtalk-stream-sdk-go)——注意事件用 `RegisterAllEventHandler`、connect 用的机器人是 `RegisterChatBotCallbackRouter`,两套别混;版本/接口会变,不在这里固化。
## 发现命令
调用任何方法前先查清楚再敲:
```
# 浏览命令组下的子命令与 flag
dws dev app event --help
# 查某方法的必填参数、类型、默认值
dws schema dev.app.event.<method>
```
按 `dws schema` 输出构造 `--flag`(flag 名 = schema 参数名)。
