Warm registry view caches before resolving mock metrics targets

Browse Source 
The mock unified snapshot resolved a metrics target per resource on a
freshly ingested registry whose view caches were still dirty, so every
resolution fell back to a scan over all source mappings, turning the
loop quadratic at demo scale. One view read builds the caches first,
making each resolution an index lookup.

Contract-Neutral: performance-only cache warm before target resolution, resolved targets unchanged
