Concurrent Chunk Management Engine - Forge

C2ME-Forge 0.2.0-forge.7 (1.20.1)

HOTFIX for forge.6 + one more performance step. Same worlds as forge.6, verified block-for-block
against unmodified generation.

FIXED
- Hard crash at world creation with mods that hook into structure terrain adaptation
  (Beardifier.compute), e.g. FDBosses / Qliphoth Awakening ("cannot inject into ... merged by
  MixinBeardifierBounds"). The Beardifier optimization no longer replaces the vanilla method: it
  skips provably-zero structure pieces by advancing vanilla's own iterators, so other mods'
  injections keep working. Pieces with mod-supplied bounding-box classes are never skipped, which
  preserves those mods' custom terrain shaping.
- Other replaced worldgen methods (aquifer, height cache, noise cell driver) now use a lower mixin
  priority so injections from other mods can apply on top instead of failing.

PERFORMANCE
- Cell-proof noise filler: whole 4x8x4 noise cells that are provably sky (density cache + aquifer
  proof) skip the per-block evaluation, and provably solid cells are written directly. About 64% of
  overworld cells are sky and 24% solid. r1000 pregeneration: -6.5% on top of forge.6
  (lab: 81.3s vs 87.0s, n=3 interleaved). Verified with a replay mode that re-evaluates every
  skipped cell through vanilla's per-block path: 409.9 million blocks, zero mismatches.

All changes verified world-identical against pure unmodified generation (Forge + Chunky only,
same seed) via block-level, noise-class and light-level comparison at r500, plus bit-exact replay
gates on every batched path. Upstream ports used under MIT with attribution.
