fix(windows): link the client as a GUI subsystem — no console window on launch

Browse Source 
The binary had no windows_subsystem attribute, so it linked as a console (CUI) app and Windows
opened a console window alongside the WinUI window on every launch (incl. the MSIX). Add
#![cfg_attr(windows, windows_subsystem = "windows")] so the windowed/MSIX launch is window-free
(verified: the built exe's PE subsystem flips from WINDOWS_CUI=3 to WINDOWS_GUI=2). To keep the CLI
paths usable, main now calls AttachConsole(ATTACH_PARENT_PROCESS) at startup — it binds to an
existing parent console only (never creates one), so --headless/--discover still print to the
launching terminal while Explorer/MSIX launches stay console-free. Adds the Win32_System_Console
windows feature.
