PTT was focus-scoped (WinForms KeyDown/KeyUp) so it died the moment the window lost focus. Add an optional system-wide path using the Raw Input API (RegisterRawInputDevices + WM_INPUT with RIDEV_INPUTSINK) instead of a WH_KEYBOARD_LL low-level hook -- the latter is the keylogger pattern AV heuristics flag, which is worse for our unsigned MinGW binary. Raw Input involves no DLL injection or global hook and passes keys through. - New VoiceCat.App/Native/RawInput.cs: P/Invoke + structs; register the keyboard sink, decode WM_INPUT to vkey/up-down, GetAsyncKeyState helper. - MainForm overrides OnHandleCreated/OnHandleDestroyed/WndProc to manage the sink and route WM_INPUT to PTT; gates the focus-scoped KeyDown/KeyUp off when system-wide is on; makes the Deactivate force-release conditional; adds a GetAsyncKeyState watchdog on the pump timer so a missed key-up (RDP/lock-screen) cannot leave PTT stuck. - VoiceSettings.SystemWidePtt (default ON) + system-wide checkbox in the Audio settings PTT section.
