Feed poller silently swallows GetFeedsToRefresh errors

[can3p]

feeder.refreshFeeds (pkg/feedops/feeder/feeder.go:83) ignores the error from GetFeedsToRefresh:

feeds, err := GetFeedsToRefresh(ctx, f.db)
// err is never checked; the loop runs over nil and the function returns nil

When the query fails (DB down, bad migration), RSS polling stops without any log line. The slog.Warn("Failed to refreshFeeds") in RunPoller never fires.

Reproduction: run the poller against a database without the rss_feeds table, or with the connection dropped. Nothing is logged and no feeds are refreshed.
