The monitor signal handlers (signal_monitor_added, signal_monitor_removed) were never disconnected during SIGUSR2 reload. Each reload accumulated additional handlers, causing multiple layer surfaces to be created when monitors were hotplugged. This fix: - Stores signal connections as class members - Disconnects them before reconnecting in bindInterfaces() - Clears stale outputs_ on reload

This PR fixes duplicate waybar layer surfaces appearing after monitor hotplug events.
The
signal_monitor_addedandsignal_monitor_removedhandlers were never disconnected during SIGUSR2 reload. Each reload accumulated additional handlers, so when monitors were hotplugged, all accumulated handlers fired and created duplicate layer surfaces.Changes:
