- heightmap.rs: read sea_level from the PNG tEXt chunk (bake writes it),
default-fallback param; new test reads_sea_level_from_text_chunk.
- client atlas_viewer.gd: load reliefmap.png (color display) instead of
heightmap.png (now 16-bit grayscale elevation, cascade-only).
- drop atlas_body_heightmaps: removed from systems-schema.sql; DROP TABLE in
import_economics MIGRATION_SQL (the PNG is the store now).
- D-202 amendment: implementation-status note (consumer + producer done),
resolving the review's 'reads done but producer pending' point.
