refactor: dataset uses closure Loader + Close callback; check-ip uses Dataset/Group
dataset.Loader[T] is now func() (*T, error) — a closure capturing its own
paths/config, so multi-file cases (LoadFiles(paths...)) work naturally.

Dataset.Close func(*T) is called with the old value after each swap, enabling
resource cleanup (e.g. geoip2.Reader.Close).

Sources.Datasets() builds a dataset.Group + three typed *Dataset[ipcohort.Cohort].
main.go now uses blGroup.Run / cityDS.Run / asnDS.Run instead of hand-rolled
atomic.Pointer + polling loops. containsInbound/OutBound accept *Dataset[Cohort].
nopSyncer handles file-only GeoIP paths (no download, just open).
