chrg6 a135c19450 Ignore the focus loss that the close's own hide of the window sends, so the exit summary keeps the session's frames. 
The review of the window close change found that hiding the active window in gfx_window_win.c exit_start makes
Windows send WM_ACTIVATEAPP(FALSE), which wnd_proc passed on to gfx_window_focus_changed(0). In play, perf.c
perf_focus_lost then asked for the session's reports, and the present thread, which runs until rt_exit_steps reaches
prof_write, wrote "frametime: at focus loss" for the whole session at its next present, with the stutter map and the
memory ranking, and started a new period. "frametime: exit" then covered only the few frames since the hide, or was
missing when none came, so a normal close no longer left the exit summary the play-test's "Normal close" item reads.

wnd_proc now returns at a focus loss once g_exit_started is set. exit_start sets it on the window thread before
ShowWindow, and the message comes on the same thread inside that call, so the check has no race. A gained focus is
still passed on.

Not reproduced before the change (it needs a play run). tests/exit_order_check.py checks statically that
WM_ACTIVATEAPP returns before gfx_window_focus_changed for a loss once g_exit_started is set and that exit_start sets
the flag before the hide; the check fails on the code before this change and passes after it. The compile check of
gfx_window_win.c passes with no new -Wall warnings.

// The Win32 back end of the window (gfx_wsys.h): the window and its message loop on a thread of their own, F11
// fullscreen, the settings NX2NAVI_WINDOW_SIZE, NX2NAVI_FULLSCREEN and NX2NAVI_MONITOR, the monitor's refresh rate, focus, the Vulkan surface.
// The swapchain and the present are gfx_present.c's. The in-game menu's keyboard and mouse come from the window
// procedure (ui/menu_win.cpp), and so do the game's (input_win.c).
//
// The process is per-monitor DPI aware (nx2navi.manifest): every size here is physical pixels, NX2NAVI_WINDOW_SIZE included,
// and the swapchain matches the screen pixel for pixel. A window moved to a monitor at another display scale keeps its
// client size (WM_GETDPISCALEDSIZE); the menu takes its text size floor from the window's DPI (gfx_window_dpi).
