Enclosure Lid V1

implemented unverified

Lid for enclosure_base_v1 (pure recipe, zero Python): a rounded top plate, an inset plug that drops into the shell interior (the lid_seat joint verifies the clearance chain), countersunk screws into two of the base's bosses, and a press-fit alignment pin pair into the other two. Match the mating dimensions via assembly.shared.
