- U-1: 'graph report' shows the paper title next to each in-KB hub (dangling
OpenAlex-id hubs are flagged), instead of bare ids.
- U-3: '--json' now includes a 'small_corpus_warning' field (null unless below
graph_min_corpus_size) instead of silently dropping the warning.
- C-9: new 'codex discover recommend <id>' wires semanticscholar.fetch_recommendations
(was implemented + tested but unreachable).
- U-4: new 'codex graph cocited <id>' wires graph.find_co_cited (likewise).
