With explicit owner approval, traced the persistent credential-issuance
rejection to a cross-transaction race in RAGcore's own dependency
injection (two independent DB transactions per request instead of one
shared transaction), fixed and deployed it in RAGcore, and verified a
working "RAGcore Sync Token" n8n credential now exists. Unblocks
workflow 3 and the RAGcoreKnowledgeProvider adapter rewrite.
