- noise_jit: Cranelift JIT codegen for multi-octave noise (baked freq/amp immediates, unrolled octave loop, external noise fn via FuncRef) - aabb: AVX-512 ray-packet slab test (16 AABBs/iter for projectile collision) - property_mask: multi-mask counting (crops/liquids/redstone in single pass, AVX-512 + scalar) - palette_codec: Bedrock XZY coordinate reorder + combined reorder-pack - byte_scan: NBT schema scanner (multi-tag SIMD byte scan + name verification) All 99 module tests pass. Both default and jit-native feature builds succeed. https://claude.ai/code/session_01CdqyUTUfjKZuk8YGJzv6LB
Add noise_cache HashMap to JitEngine for compile_noise/get_noise lifecycle. Import CachedNoiseKernel from noise_jit module. https://claude.ai/code/session_01CdqyUTUfjKZuk8YGJzv6LB

Summary
Fills all remaining gaps from the Pumpkin/Mindcraft jitson shopping list, bringing all 12 hotspots to full implementation in ndarray's HPC module.
New capabilities (+1,289 lines across 7 files):
JIT noise codegen (noise_jit.rs, 533 lines) — Cranelift IR for multi-octave Perlin. Unrolled octave loop with baked f64 freq/amp immediates. External base noise via FuncRef.
Ray-packet AVX-512 (aabb.rs, +155 lines) — 16-wide slab test for projectile collision.
Multi-mask tick counting (property_mask.rs, +162 lines) — crops/liquids/redstone in single pass. AVX-512: 8 states/iter × N masks.
Bedrock coordinate reorder (palette_codec.rs, +192 lines) — Java Y-major ↔ Bedrock XZY permutation + combined pack.
NBT schema scanner (byte_scan.rs, +234 lines) — multi-tag SIMD search + name verification. Batch mode for 1024-chunk regions.
