NX2navi/runtime/gfx_present.c
chrg6 a42648e27a Add the game's native HDR, render at the monitor's real size, and refresh movie frames on the GPU. 
HDR is now a menu row: Off, Enhanced (the runtime's own HDR tonemap) or Native. Native reports an HDR10 display to
the game with the settings' peak and paper white; the game then renders its own HDR picture and presents it as PQ in
A2B10G10R10, which goes to the HDR10 swapchain as it is. The peak, game, HUD and (for Enhanced) hue rows follow it.

The build kit's link left out runtime/nx2navi.rc, so the game had no manifest and no icon: without per-monitor DPI
awareness, a 5120x2160 monitor at 150 % gave a 3413x1440 window that Windows stretched. It is compiled with windres
and linked again.

The movie decoder's frames are copied into the game's buffer by the host; the back end is now told of that write, so
the GPU's copy of the buffer does not keep older or empty bytes (green stripes in NV12).

A longjmp out of the game's JPEG decoder now logs the guest functions that called it, to trace a later crash.

// Vulkan surface and swapchain, present blit, 60 Hz vsync thread, focus: the window-system-free half of the window
// (the other half: gfx_window_win.c with Win32, gfx_window_sdl.c with SDL, through gfx_wsys.h).
// Contains code Copyright (c) 2026 Peiikai, Copyright (c) 2026 MacNativeGames contributors (MIT; see
// THIRD_PARTY_NOTICES.md).
//
// Threads: the window thread (the back end's) owns the window and never runs guest code. The vsync thread signals the
// bound system events. Presents come from any host thread (the back end's present worker) and take g_pl; every queue
// submission takes the recursive queue lock (vk_queue_lock). The swapchain is rebuilt lazily: a resize only marks it
// dirty (gfx_window_mark_dirty), the next present (or gfx_window_resize) rebuilds it.
//
// The in-game menu (ui/menu.h) draws over the game image in the present's command buffer, after the blit. The window's
// size and fullscreen state are the settings NX2NAVI_WINDOW_SIZE and NX2NAVI_FULLSCREEN, which the back end applies at start
// and whenever a cfg_set changes them (window_settings_live -> gfx_window_apply_settings).
