chore: bump codec fe69506, kernel ae28f66, graph 892f942

The codec writes R2018 AuxHeader maintenance fields as RL, so AutoCAD no
longer reads a 2018 save as student-made. The kernel drops zero-area
spikes before triangulating, so a hatch whose boundary folds back on
itself fills on screen instead of vanishing.

Fixes #1564
Fixes #1569
