the directory picker moves to the platform

kanban wanted the same one and a plugin cannot import from a sibling, so it now
lives in the officerdev barrel and this imports it from there. nothing in it was
fofos-specific — it browses the owner's home over the platform's file API.

deleted here rather than kept as a second copy. the copy that drifts is always the
one somebody is looking at.
