Axel Meyer 7adcb407fa Add map builder that turns AST + atlas registry into v2 JSON
Validates atlas declarations against the registry, resolves tile
names per atlas, bounds-checks each cell, and emits a flat
row-major (y*w + x) GID array per layer. Roof block is only
serialised when at least one roof directive was present so empty
maps stay compact.
