Add autostart functionality and power management for Raspberry Pi
- Enhanced install.sh with comprehensive autostart workflow: * XDG autostart entry (desktop environment) * systemd user service (most reliable) * LXDE autostart support (Raspberry Pi OS) * Cron fallback (@reboot) * Terminal mode enabled for debugging - Added Raspberry Pi power management features: * Disable HDMI screen blanking * Prevent CPU power saving (performance mode) * Disable system sleep/suspend * X11 screensaver disabled * Display power management (DPMS) disabled - Fixed sudo compatibility: * Properly detects actual user when run with sudo * Correct file ownership for user configs * systemctl --user works correctly - Player launches in terminal for error visibility - Autostart configured to use start.sh (watchdog with auto-restart)
