Lucas WintherandClaude Opus 5.5 5297b8ead9 feat(prefs): show events that haven't started to new readers
A new reader should see what's coming before deciding they don't want
it. It's set at first-run setup rather than in the defaults, so an
existing install whose saved prefs predate the field keeps its answer
instead of having it switched on underneath it.
