satellite.launch

Dev: search for a safe crash site around the calling player using the exact same acceptance checks a control computer's lock-in uses (topology, water, unevenness, safezones, obstructions), then launch the full orbital descent there. Not a full session replica: searches around the player rather than a computer's semi-random targeting center, always does a fresh scan (no thruster-history reuse), and has no owning computer (no countdown screen, radius floor still enforced, no-build volume self-despawns after impact instead of being computer-managed): satellite.launch [radius]
