GridForge v6.0.0

GridForge v6 is a breaking release centered on the GridWorld refactor. The library now uses explicit world ownership instead of process-wide global runtime state, making it possible to run multiple isolated worlds in the same process without cross-world leakage.

Highlights

• Introduced GridWorld as the primary runtime owner for voxel size, spatial hashing, active grids, lifecycle, events, and world-space lookup.
• Moved tracing, blockers, occupant tracking, scan queries, and obstacle mutation to explicit world scope.
• Replaced global voxel identity with WorldVoxelIndex, making voxel and grid references world-scoped and safer across teardown and slot reuse.
• Rebuilt tests, benchmarks, README guidance, and examples around the new explicit-world model.
• Moved project documentation into docs/, added wiki sync automation, and refreshed build/release workflows.

Breaking Changes

• GlobalGridManager has been removed. Runtime operations now require an explicit GridWorld.
• GlobalVoxelIndex has been replaced by WorldVoxelIndex.
• VoxelGrid.GlobalIndex has been renamed to GridIndex and is only unique within its owning world.
• GridConfiguration is now pure input data; snapping and normalization now happen during world registration.
• GridTracer, blockers, scan APIs, and occupant/obstacle flows now operate against an explicit world context.

Upgrade Notes

• Create a GridWorld for each runtime world and route grid registration and lookup through it.
• Replace GlobalVoxelIndex usages with WorldVoxelIndex.
• Audit any code that assumed process-wide world state or globally unique grid indices.
