Function compute_required_protocols 

pub fn compute_required_protocols(
    queried_tables: &[&str],
    registry: &ProtocolRegistry,
) -> HashSet<String>

Given a set of queried table names (e.g., ["tcp", "ipv4"]), returns all protocols that must be parsed, including transitive dependencies.

Arguments
