Module threejs-water

Oceans, lakes and rivers for three.js (WebGPU / TSL), from an ant on the beach to orbit:

• Ocean: a sea-level surface for flat worlds and planets, Gerstner waves, refraction, depth-tinted colour, shoreline foam and whitecaps, one draw call at every altitude.
• Rivers: streamed river surfaces for a threejs-biomes world, with flow-mapped water.
• Bounded-map hydrology (computeHydrology): depression filling, flow routing and accumulation, rivers and lakes, plus height modifiers that carve the rivers; Lakes draws it.
• Queries (waterAt, hydrologyWaterAt, Ocean.waterAt) for gameplay and buoyancy.
