meta/library-enrichment overview

Reusable batch enrichment of the process library: survey backlogs and library coverage in parallel, recall prior enrichment knowledge from kip, synthesize a candidate slate, get owner approval, author the approved items in parallel (design -> generate -> adversarial proof-driven quality gate), integrate them into backlogs and indexes, capture durable insights back into kip, and finish with an owner sign-off. Re-run it any time to enrich the library further — each run builds on the facts the previous runs asserted into kip.
