- Add missing isSelectAll() method to RuntimeQuery class
- Update RuntimeQueryTest to use compile() before filter() since filter()
expects pre-compiled query arrays, not Query objects
- Remove incorrect break statement in Realtime::getSubscribers() that was
stopping iteration after the first matching channel, causing subscribers
to not be found for subsequent channels
- Use local variable $subscriptionsByChannel to avoid unused variable warning
