README pagination example uses an undefined SDKClient identifier

Summary

The pagination example in both the English and Chinese README uses an undefined SDKClient identifier after creating the client as client.

Affected version

• @larksuiteoapi/node-sdk 1.73.0
• main at f54b49f3566c52b54c598194b7ed3015e3e24224

Location

• README.md, pagination example near line 152
• README.zh.md, pagination example near line 174

Both currently contain:

const listIterator = await SDKClient.contact.user.listWithIterator({

The surrounding quick-start code declares const client = new lark.Client(...); it never defines SDKClient.

Expected behavior

The example should call client.contact.user.listWithIterator(...), matching the instantiated client used by the surrounding documentation.

Actual behavior

Copying the example produces ReferenceError: SDKClient is not defined (or a TypeScript unresolved-name error).

Impact

The first documented pagination example cannot run as written, and the same error is duplicated across both maintained locales.

Open README.md near line 152 and README.zh.md near line 174, then compare the pagination snippets with the surrounding quick-start code. Update both examples so they use the instantiated client, and verify that neither contains the undefined SDKClient identifier.
