Battlify 0.9.3 — Keep-awake on battery

Always Active: optional "Also keep awake on battery"

"Always Active" still defaults to AC-power-only (it releases when you unplug), but a new opt-in sub-toggle in Settings lets it keep the Mac awake with the lid closed on battery too. Off by default because a closed, unventilated Mac kept awake on battery drains fast and can run hot — the temperature guardrail still applies as a safety net, and the display/keyboard backlight still switch off to save power.
