Bug Fix
fix(entities): use get_graph_storage() instead of storage.graph in maintain Step 5
In v10.55.0, memory_quality(action='maintain') ran entity extraction correctly (entities_found > 0) but never wrote any links to the graph (links_stored: 0). Root cause: Step 5 in quality.py checked storage.graph, which is never set on storage objects. All other graph handlers use get_graph_storage() — Step 5 now follows the same pattern.
Upgrade from v10.55.0 is recommended if you use entity extraction.
