Axel Meyer 99d00bd115 Rewrite draw_layer for atlas-handle + uv rendering; bump to 0.3.0 ...

draw_layer now samples tile sub-rectangles from the atlas diffuse
texture via the ADR-0044 source-rect render primitive (13-arg
draw_sprite_transform). load_textures gains a walkable field in
tile-records (from atlas JSON) so gameplay queries work after the
tiles-dir is removed. load_tilemap falls back to an atlas-bootstrap
stub when the legacy tilemap JSON is absent, allowing maps.load to
succeed before load_textures is called. Texture loading uses pcall
to degrade gracefully in headless environments. Bumps lib version to
0.3.0 to flag the breaking change in tile-record shape (id is now
integer, name is the stable string identifier).
