wip(standalone): shape-world look round, stopped by low memory mid-check

The look round was stopped by the system for low memory (not a code fault) while
checking worker-independent hashes and refreshed owner-distance comparisons.
Saved state, not yet reviewed:
- passage floors carry rock detail (flat-floor check passes)
- tunnel radius step between joined segments 0.0000 voxels across 240 joins (was 2.9156)
- 3-octave surface relief
- cold 64 m full detail 0.982 s (0.703 shapes + 0.279 mesh), whole view 2.490 s, 8 workers
Pending: determinism 1 vs 6 workers, owner-distance numbers, final captures, report.
