This implement session tracks progress through the `@juicesharp/rpiv-todo` checklist overlay —
the selected todo provider (perk's own checkpoint surface has stepped aside). Seed the overlay
from the plan body's `## Steps` numbered list — one checklist item per step, in order — then
mark each item complete as you finish it, using the overlay's own controls; perk's
`[WIP:n]`/`[DONE:n]` markers are not needed here. If the plan has no `## Steps` list there is
nothing to seed — let the overlay behave as its defaults suggest.
