Added generation history

- World-local pack epochs preserve generated chunks across restart-only updates
- Kernel catalogs and source seals retain executable generation behavior across jar changes
- Crash-safe ownership, boundary, registry, semantic, and mantle records survive activation changes
- New terrain blends lower surfaces and inverted ceilings against frozen historical boundaries
- Cave, object, structure, biome, and hydrology work respects activation ownership
- Find commands merge recorded facts with eligible active predictions for biomes, regions, structures, objects, and rivers
- Bukkit, Fabric, Forge, and NeoForge route generation through retained runtime scopes
- Shutdown ordering preserves class-loader resources until world and service cleanup finishes
- Tests cover activation chains, failure recovery, retained registries, bounded lookup, and transition geometry
