- Restructure folder hierarchy: max 4 .rs per dir using subfolders (ops/operations -> brush/ + shaping/, model/ -> world/, io/* -> subtypes, etc.) - Fix golden_test.rs comment, extract BrushApply helper, add World::with_heightmap - Implement 6 layer data generators (Caves, River, Frost, Trees, Biome, Resources) with noise-based (OpenSimplex) and terrain-derived algorithms - Fix clippy warnings, dead code cleanup, import path fixes - GUI: add Erode&Fill tool modes with radio buttons/sliders/apply_tool - GUI: add Layers panel with 6 checkboxes + CPU viewport overlay rendering
