Trait for receiving monitor data from various sources.

Implementations of this trait provide monitor snapshots from different backends - file polling, message bus subscriptions, or in-memory channels.

let mut source = FileSource::new("monitor.json");
if let Some(snapshot) = source.poll() {
    println!("Got {} modules", snapshot.len());
}
