Defiled Lands Reforged

## Defiled Lands Reforged v1.11 — Minecraft 1.20.1

### Added
- **Scarlite Armor** — a full four-piece set (helmet, chestplate, leggings, boots), ported from the 1.12 implementation along with its custom 3D model: a horned, crested helm, a two-part cuirass, spiked pauldrons, and plated greaves and boots.
  - Diamond-tier protection (3 / 6 / 8 / 3) and 2.0 armor toughness, with noticeably higher durability and enchantability than diamond.
  - Crafted and repaired with Scarlite gems.
  - The leggings render correctly here: in the original 1.12 implementation the leg and boot pieces shared a single model part, so the greaves were always hidden and the boots wrongly rendered the thigh plating. The two are now separate parts.

### Fixed
- **Stair corner models** — Defiled Stone, Defiled Sandstone, Defiled Stone Brick and Tenebra stairs shipped with only the `straight` shape defined. Every inner and outer corner fell back to the missing-model texture. All four stairs now have proper inner/outer models and the complete set of 40 blockstate variants.
- **Server stall near Blastem** — the Blastem proximity scan read blocks through `Level#getBlockState`, which synchronously loads (and can generate) neighbouring chunks on the server thread whenever the scan crosses a chunk border. It now reads only chunks already resident in memory, and confirms the entire explosion radius is loaded before detonating.
