From ebdf809e0723ba3d32794278c72e4cd844cea498 Mon Sep 17 00:00:00 2001 From: "Danilo M." Date: Fri, 17 Jul 2026 10:34:54 +0200 Subject: feat: daemon status, restart, live preview Add daemon.py module to control hyprsunset daemon via subprocess: - is_running() checks daemon status using pgrep - live_preview() pushes temperature/gamma/identity to running daemon via hyprctl - restart() kills existing daemon and launches new detached process All subprocess calls are mocked in tests; no real processes are touched.
