feat(camping): three-tier ore detector with private-chest faraday cage

New basic/improved/advanced detectors (8/16/32 block range). Aim and
right-click to ping the nearest ore on the view ray; pitch-coded sound
and action-bar text show distance and ore type. Any ore within 4 blocks
of a silverlabs:private_chest is hidden — chests act as faraday cages
so claimed bases stay private from neighbours' detectors.
