Catalog bridge

The vault is mapped back into the product test library

This bridge answers the operational question: which catalog tests, guided paths, and product hooks can draw fresh questions from the reusable 10k+ vault instead of depending only on the curated live prompt set.

Reviewed seeds can now become live tests and funnels

The vault no longer only reports inventory. Approved seed records have adapters into the current diagnostic and funnel question shapes, so we can migrate one surface at a time instead of rewriting the runner.
