Reject oversized logo responses instead of silently truncating them,
which could persist corrupt image bytes as a valid logo.
Tighten ownership substring matching with a length-ratio guard so a
short label root no longer attributes unrelated domains to a vendor.
Render the worker confidence threshold when set to zero by testing
against nil, so an explicit "accept all" value is not dropped by Helm's
falsy-numeric truthiness.
Sanitize and bound per-agent error text before persisting it to the
enrichment metadata column to avoid leaking unbounded internal detail.
