Bonsai's Gantt chart code special-cases BASELINE schedules by following
IsDeclaredBy[0].RelatingObject to find a parent comparison schedule.
Our schedule has no such relationship, causing an IndexError that
silently prevents the Gantt from rendering.

PLANNED is the correct type for a forward-looking construction programme.
Also updates the CLAUDE.md recipe to use PLANNED.
