feat(rendering): on-screen debug overlay showing current biome and coordinates

Browse Source 
Asset-free bitmap-text overlay: a 5x7 font (glyphs defined as verifiable ASCII-art) drawn as solid quads through a tiny 2D shader, white text with a drop shadow for legibility over any background. Renders 'BIOME: <name>' and 'XYZ: x, y, z' top-left, updating live. Adds Shader.SetVector2 and WorldGenerator.BiomeNameAt support; text scale and spawn-height offset read from Configuration.
