Now that -r/--run and -x/--exec cover normal use, --mount/--umount/--cleanup are debug-only escape hatches not worth a short letter. Reassigned their long_options codes to long-option-only constants (options::mount/umount/ cleanup) and dropped m:/u:/c: from getopt_long's own short-options string. Updated the fixture smoke test (tests/run_test.py) and docs, which invoked -m/-u/-c directly.
