Add a PruneChannelEvents query that bounds the channel_events table by both size and age in a single statement: an id-keyset offset enforces a maximum event count and a timestamp filter enforces a retention window, OR-joined so each limit applies independently. The query returns the number of rows deleted so callers can surface pruning activity. Add a standalone timestamp index so the global age-based prune does not scan the full table. The existing composite index leads with channel_id and cannot serve a channel-agnostic timestamp filter.
