Function should_dispatch 

pub fn should_dispatch(project: &ProjectConfig, chain: &[Option<bool>]) -> bool

Top-level cluster-dispatch decision.

Returns false when FLODL_INTERNAL_CLUSTER_JSON is set — that signals we’re a recursive fdl invocation on a remote host that the launcher’s ssh fan-out reached, and we should fall through to normal dispatch. Otherwise delegates to config::cluster_dispatch_enabled.
