Onboarding + loop flow for a hands-off demo; GoalTarget 4->2

Lap-1 Fabricator affordable (StartingOre 50->90); mine prompt shows IN the room;
Return no longer false-completes on death (WasOnExpedition latch + soft timeout,
never the 1-tick Returning edge); HUD keeps room/siege/ammo cues during combat
steps; Welcome needs an explicit confirm; READY panel shows FINAL DEFENSE when
goal-full; dev Force-Each-Launch hidden from public Settings. GoalProgress.Target
4->2 (~10-20 min demo). Onboarding tests updated to the new contracts (456/456).
