fix: drop RAGcore's opaque version UUID from the fallback answer sentence

Browse Source 
document_version_id is an internal UUID, not a human-meaningful version like
the demo corpus's markdown frontmatter -- confirmed live it made the fallback
answer read as "Per \"vehicle-checkout-procedure.md\" (v2e139422-b10b-...)".
Still shown on the source card itself, just not in the composed sentence.
