Ore Deposit World Gen Implementation

[starpanda24825]

Added cluster-based ore vein generation using create's layered deposit shapes

• using rare cluster origins that spawn multiple deposits nearby, mimicking how Create places its striated ores (Asurine, Ochrum, etc)
• ported Create's LayeredOreFeature algorithm: sphere-based deposits with gradients, layer bands, and radial falloff. single deposit size stays fixed at 32 to match Create's visual style, but if u choose you want to make the deposit tiers affect the actual SIZE of vein not number of veins in a cluster, then edit this respectivelt
• implemented two-tier rarity system:
  • cluster-level: rare region-based origins (configurable via averageChunksPerCluster)
  • intra-cluster: deposit spacing (configurable via chunksBetweenDeposits)
  • tier size (LARGE/MEDIUM/SMALL) now determines number of deposits per cluster, not size of deposit
• correct per-ore Y-levels to match vanilla counterparts (diamond, iron, copper, etc).
  netherite reuses diamond's overworld range since this mod is overworld-only (right?)
• add /deposits debug command (dev-only, src/dev/java) to verify clusters spawn:
  • /deposits locate [radius] - scan area and show nearest cluster origins as /tp links
  • /deposits stats - print current config (spacing, deposits/cluster, Y ranges)
• add LayeredDepositPattern for per-ore layer definitions (stone types, sizes, weights)
  so not every deposit of the same ore looks identical
• wired biome selectors from config into actual biome filtering (was configured but unused)
• optimised the code as much as I possibly could

Remains:

• Register all the deepslate variants of ore deposits alongside their respective assets (not urgent)
• use per-ore Y-levels of these ore deposit versions to match the vanilla deepslate counterparts (not urgent)

There's too much for me to fully review right now, but just my initial thought is here

This is wonderfully complicated. Just, uh... you only need an if statement for conditional compilation...
