v0.3.0

Fixed

• -s/--sleep is no longer skipped when there is nothing to force-quit. Every
  mode that found zero victims exited before reaching the sleep code, so
  fq -o -y -s — the natural "quit everything else, then sleep" command —
  silently did nothing at all when every other application was protected or
  the application running the terminal was the only one left. The sleep is now
  a step of its own that every mode reaches; with nothing to quit and without
  -y, fq asks about the sleep alone ("Put the Mac to sleep? [y/N]") instead
  of asking to force-quit zero applications.
• The sleep is no longer asked for twice: the combined "force quit … and put
  the Mac to sleep?" confirmation now covers the sleep, so a single y both
  quits and sleeps. This was still broken when naming an application on the
  command line (fq -s Safari), which asked a second time after the first y
  and then treated the second, unanswered prompt as a decline — so the Mac was
  never put to sleep.

Added

• FQ_SLEEP_CMD overrides the program used to put the Mac to sleep, and
  FQ_APPS_FILE (pid name lines) overrides application enumeration. Both
  exist so the test suite can exercise the real code paths without touching
  running applications or actually sleeping the machine.

Tests

• test/test_sleep.sh covers the sleep behaviour end to end, driven through
  the built executable with a synthetic application list and a stub sleep
  command: nothing-to-quit still sleeps (including a machine with no
  applications at all), one confirmation never asks twice (for --others,
  --pid, and a named application alike), a declined confirmation never
  sleeps, and a refused protected application exits 1 without sleeping.
