fix: forțează SetForegroundWindow prin ALT-key pentru anti focus-stealing

Browse Source 
pygetwindow.activate() raporta succes dar Windows refuza silent ridicarea
ferestrei TS (confirmat în audit: window_focused cu titlul corect, dar
screenshot-ul manual tot prindea app-ul de deasupra). Trucul standard:
keybd_event(ALT) resetează focus-lock-ul, apoi SetForegroundWindow via
ctypes pe hwnd direct. Fallback la win.activate() dacă lipsește _hWnd.

pygetwindow.activate() folosește SetForegroundWindow, care Windows îl
refuză silent când procesul apelant nu e cel care deține focus-ul
(protecția anti focus-stealing introdusă în Win2000). Trucul standard:
trimiți un ALT press/release ca să resetezi lock-ul, apoi restore +
SetForegroundWindow prin ctypes pe hwnd direct.
