Snapshot of one cell across every mutable channel. bytes holds
[terrain, elevation, flags, riverDir, roadBits, riverInBits, ...featureLevels];
meta is a deep clone of the cell's metadata record (null = no metadata).
Derived data (water surfaces, shore distances) is intentionally excluded —
ChunkManager.update() recomputes it for dirty regions.
