justfile: erase recipes use the prog_wide default (drop pinned --v-hack-path)

fast-projected / full no longer pin v_hack_full.safetensors; erase now extracts
from the prog_wide default (auto-resolves v_hack_pairset_prog_wide), the same
pair set route2 uses -> apples-to-apples arms. Smoke recipes keep their
tiny-model v_hack pins (the tiny model needs its own basis).
