[P1] Avoid updating Tk widgets from background threads
The Monitor thread writes directly to the ScrolledText widget (self.output.configure/insert/see) while run executes on a separate daemon thread. Tkinter is not thread‑safe, so these updates can raise RuntimeError/TclError or corrupt the GUI, especially when the window is closed while a fetch is in flight. Widget updates should be marshaled back to the main thread (e.g., via after or a queue) and threads joined before destroying the UI.
