v0.1.2 Hotfix

[0.1.2] - 2026-05-23

Hotfix for a save crash reported by multiple users on the ModDB page (SimonBBallin, Sir_Capon).

Fixed

• Save no longer crashes with NullReferenceException when the selection contains entities. The vanilla BlockSchematic.AddArea captures every entity in the region (mobs, dropped items, falling blocks, projectiles) and runs Entity.OnStoreCollectibleMappings on each, which NREs for any entity with a null collectible reference. New BlueprintStore.CaptureBlocksOnly method builds the schematic from blocks only, bypassing AddArea entirely. Block entities (chest contents, sign text, chisel voxel data) are also skipped for now; they aren't read by any v0.1.x feature. Per-cell block-entity capture with proper try/catch returns when Phase 4 chisel overlay needs it.
