Use the active overlay graph read model for search_graph relationship-only requests while keeping connected-neighbor enrichment on canonical ids until that path is separately implemented.
Add active_edges CTE support to cbm_store_search_overlay_view so relationship filters, entry-point filters, and degree filters can use visible canonical edges plus latest ready owned overlay edges keyed by qualified name.
Make search degree-filter wrapping fail explicitly on allocation or SQL truncation instead of silently truncating generated SQL.
