startBackgroundFetch assigned the field from its own goroutine, and only after the initial fetch had completed, while the UI thread reads it in triggerImmediateFetch on every repo switch, with no synchronization. Create the channel in startBackgroundRoutines instead, which runs on the UI thread before the fetch goroutine is spawned; everything the UI thread does afterwards is ordered after the write, so the read is race-free without any locking. To make this possible, goEvery now takes the retrigger channel as a parameter instead of creating and returning it; callers that have no use for a retrigger channel pass nil, and a nil channel in a select is simply never ready. As a side effect, a repo switch that happens before the fetch loop has started (during the intro popup or the initial fetch) now latches a trigger and causes an immediate fetch once the loop is running, where previously it was silently dropped.
