#2486 (thanks @adminwat): normalize dict-shaped hyperedge members to ids
(or drop with a warning) so a malformed hyperedge can't abort a completed
merge with a TypeError.
#2484 (thanks @sortakool; approach from @oleksii-tumanov's #1691):
merge-graphs relabels hyperedge member ids and ids with the repo prefix,
unions both inputs' hyperedges instead of clobbering, and writes both
persistence slots.
#2485 (thanks @sortakool): build_from_json reads hyperedges from the
top-level and nested slots; a full validation wipeout is reported loudly.
#2490 (thanks @PapiScholz): the skill Step-5 flow passes curated
community_labels to to_json, so graph.json ships community_name.
