feat(resources): add park-2 booth Stack (stage tier)

New real booth, same tier as park-buzi: tracks stage, pinned stage-<sha>,
own park_2_* secret refs. Periphery had the known /etc/komodo root_directory
permission bug on --user install (wiki gotcha #9); fixed and confirmed OK
in Core before adding this Stack.
