Bake deduplicated section texture lists (UTEX) and read them at runtime so texture warm/prefetch no longer scans every instance. Evict PACK sections outside a 16 km keep ring and cap mesh/nodedata/texture warm caches to stop RAM and apply cost from growing without bound during long fast camera flight. - Bake v11 (format=4): UMES + UTEX + CHNK; mesh/texture ordering by frequency - Runtime: incremental UTEX warm, adaptive apply slices, preempt/catchup tuning - Unload: track instances per section, Region erase, pack pool release - LRU: mesh/nodedata (2000, ref-counted), warmed textures (2048) - Bench/diagnostics: unload and cache eviction counters - Fix pack instance erase in Region; resolve duplicate helper symbols
