Method is_edge_alive

atomic-core/src/output/alive/retrieve/options.rs:197–199

Check if a forward edge should be followed during traversal. A `BlockDeleted` / `FolderDeleted` edge is **never** an alive forward edge. In the additive model a deletion is recorded by adding a new edge with the `DELETED` flag *alongside* the original `Block`/`Folder` edge — the original stays in the B-tree forever. Reachability of the destination always comes from the original edge, which is f
