Bug Description and Steps to Reproduce

Bug Description

OnUserStatusChanged is not dispatched when a subscribed user's online/offline status actually changes. Relogin / calling subscribeUsersStatus again still returns the correct snapshot, so the problem is in the change-detection gate, not in subscription or server presence data.

Root Cause

In internal/interaction/subscription.go → setUserState:

Correct (v3.8.3-patch.10):

    change[v.UserID] = v.OnlinePlatformIDs  // dispatch only when UNCHANGED — inverted!
}
if !slices.Equal(status.online, v.OnlinePlatformIDs) {
    change[v.UserID] = v.OnlinePlatformIDs  // dispatch only when changed
}

### Screenshots Link

if equal(status.online, v.OnlinePlatformIDs) {
    change[v.UserID] = v.OnlinePlatformIDs  // dispatch only when UNCHANGED — inverted!
}
