Add Danger Ores - Voronoi map#1568

Conversation
A new Danger Ores variation whose ore field is partitioned into irregular Voronoi cells. Each cell is flooded with one main ore ([item=iron-ore] [item=copper-ore] [item=coal] [item=stone]) plus the usual minor mix; no two touching cells share a main ore, and every map seed produces a fresh arrangement. Layout engine (modules/voronoi_layout.lua, pure Lua / unit-tested): places jittered-grid seed points on a toroidal super-tile (seeded from the map), runs Lloyd relaxation for even cells, assigns each tile to its nearest seed (smooth, tile-resolution boundaries), then 4-colours the cell-adjacency graph with DSATUR so adjacent cells never share an ore. The layout rebuilds deterministically from the map seed, so nothing is persisted. Stone is kept scarce by using the 4th colour only when forced. Includes builder, preset, 4-ore config, scenario template, and a map preview. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
So players can vote for the map (matches the review on the Tetrominoes PR). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Danger Ores – Voronoi
A new Danger Ores preset where the ore field is partitioned into irregular Voronoi cells. Each cell is one main ore (iron / copper / coal / stone) with the others sprinkled in at low ratio — no two touching cells share a main ore, so every cell border is a colour change. Every map seed lays the cells out differently.
How it works
modules/voronoi_layout.lua— pure-Lua layout engine (no Factorio deps, standalone test file). Places jittered-grid seeds on a toroidal super-tile (seeded from the map), runs Lloyd relaxation for even cells, assigns each tile to its nearest seed (smooth, tile-resolution boundaries), then 4-colours the cell-adjacency graph (DSATUR, lowest-first so stone stays scarce). Guarantees: full coverage, clean borders, deterministic from the map seed (nothing persisted).modules/main_ores_voronoi.lua— builder;CELL_SIZE,SEED_SPACING,RELAXATIONknobs.config/voronoi_ores.lua,presets/danger_ore_voronoi.lua,scenario_templates/danger-ore-voronoi/.Everything else (spawn, terraforming, water, enemies, build-on-ore rules) inherits the Danger Ores defaults.
