Move integrity-focused tests into new 'integrity' group: - test_null_04.sh -> test_integrity_01.sh - test_loop_08.sh -> test_integrity_02.sh Move recovery-focused tests into new 'recover' group: - test_generic_04.sh -> test_recover_01.sh - test_generic_05.sh -> test_recover_02.sh - test_generic_11.sh -> test_recover_03.sh - test_generic_14.sh -> test_recover_04.sh Update Makefile to reflect the reorganization.
