Add -renderdoc <path> and -renderdoc-frame N[,C], writing one .rdc per selected dump frame. RenderDoc's own triggers cannot reach gsrunner on a Wayland session. It polls only X11/xcb for the capture key, so PlatformHasKeyInput() is false and F12 is never seen. Target control cannot drive it either: RenderDoc hooks only the core EGL entry points, while GLContextEGL prefers eglGetPlatformDisplayEXT and eglCreatePlatformWindowSurfaceEXT, so no native window is ever registered for the surface and there is nothing to attach a capture to. The in-application API sidesteps both -- StartFrameCapture(nullptr, nullptr) captures the active device whatever the windowing system, and needs no keypress, so a headless dump replay can capture unattended. Captures open and close at present boundaries in Host::BeginPresentFrame(), which runs on the GS thread with the frame's work submitted but not yet presented. RenderDoc must already be in the process, since it installs its hooks from its library constructor. A late dlopen hands back a working API whose hooks were never installed and then captures nothing, so that case is refused with the LD_PRELOAD command to use instead. Verified on aarch64/Asahi against a God of War II dump. Vulkan surfaceless produces a valid capture: 351 actions, 218 draws, 99 textures, render target carrying real image data. Windowed Vulkan cannot work under RenderDoc's layer at all, which does not advertise VK_KHR_wayland_surface. GL captures record correct events and texture contents but replay with black render targets on Honeykrisp. 3rdparty/include/renderdoc_app.h is RenderDoc's MIT-licensed in-application API header, vendored verbatim.
