详细描述

Deterministic, caller-driven equivalent of PcgTerrainWatcher's hierarchy diff.

A scan is staged with beginScan/addTerrain and published with commitScan. The first successful scan seeds the cache without reporting creation, matching Pcg's startup CacheExistingTerrains behavior. Later scans report creations in current-scan order, followed by removals in prior-scan order.

@ownership Owns copied terrain ids and changes; retains no scene object or callback. @thread Caller-thread affine. No method invokes script or user callbacks.
