Check group full-sync state

The following Commercial diagnostics compare local group data with synchronized state:

import { checkGroupMemberFullSync, checkLocalGroupFullSync } from '@/uni_modules/unix-openim-sdk'

const groupsReady = await checkLocalGroupFullSync()
const membersReady = await checkGroupMemberFullSync(groupID)

Use them for recovery diagnostics and gate refreshes, not as a replacement for normal group/member queries. Retry with bounded backoff after synchronization events.
