No Structure Overlap

3.0.1

• Synced release with the final bounding-box codebase
• Pure StructureStart box tracking (StructureBoundingBoxTracker)
• Read-only commands: /nostructureoverlap status|info|structures
• Docs cleanup

3.0.0

Major rewrite — structure overlap prevention now uses real vanilla bounding boxes.

Added

• Compare StructureStart.getBoundingBox() after piece layout (including jigsaw)
• Cancel with INVALID_START before the structure is stored or built
• Block only when different structure registry ids intersect
• Optional 3D or 2D overlap checks
• Whitelist / blacklist / per-structure enable filters

Removed

• Estimated sizes / center-distance checks
• Old early-intercept / placement-validator approaches
• Runtime toggle and cleanup commands

Notes

• Minecraft 1.21.1 / NeoForge 21.1.x
• Server-side worldgen mod (players do not need it on dedicated servers)
• Config: config/nostructureoverlap-common.toml
