Caves Everywhere

# v1.0.0 - The Abyss Awakens (Initial Release)

Welcome to the very first official release of Caves Everywhere! 
This colossal update establishes the foundation of our new, terrifyingly deep Overworld.

### ✨ Features Added
* Expanded World Height: The Overworld generation is now stretched to a massive 512 blocks.
* Subterranean Oceans: Added deep, dark underground oceans at the bottom of the world (Y = -64 to -16).
* Abyssal Ancient Cities: Ancient Cities and the Deep Dark biome now naturally generate along the cliffs and shores of the new underground seas.
* Sky-High Safe Havens: Capped solid terrain generation at Y=448, leaving the space up to Y=512 as an open void for secure, mob-free sky bases.
* Scaling Difficulty: Adapted the environment so challenges become deadlier in the extreme depths.

### ⚙️ Technical Notes
* Built and optimized exclusively for NeoForge 1.21.1.
* Important: This mod takes full control of the Overworld noise generation and is inherently incompatible with other full terrain overhauls (like Terralith or Tectonic).
