Subject: [PATCH] fix: free plot_window in delete_all_windows

initialize_gpu_mem_plot() allocates plot->plot_window with newwin()
but delete_all_windows() only calls delwin() on plots[i].win,
leaking the plot_window. This leaks one WINDOW struct per chart
on every resize (Ctrl+L) or monitored-GPU-set change that triggers
delete_all_windows() followed by initialize_all_windows().
