chore: bump codec d28fd71, kernel a03e4f0, graph 79bdc4b

Codec: PRs #71-#74 merged (MPOLYGON layout, multiline ATTDEF/ATTRIB DXF,
DXF MATERIAL/ACSH matrix, restorable SAT/SAB + history roots) and issues
#55 #64-#69 fixed. EntityType now boxes Surface, Extended, Table,
MultiLeader and Helix (2344 B -> 848 B per entity): construction sites
wrap in Box, the entity traits forward through Box, and the python
plugin generator converts with into(). Kernel: PR #70 (cuboid ring
winding).
