Merged with applezra's follow-ups on the same branch: the sun shadow filter narrowed by the shadow map scale
(translator patch 0011), anisotropic filtering forced only on tiling samplers, and TOTK_DUMP_UBO with a vec4 count.
Conflicts with dev: cfg.c (names, display section, defaults next to aspect and device_profile), menu.cpp (the new rows
after the aspect row), vk_texture.c (the pool alias check takes scale == 1 and dev's bind_pool_memory size argument),
build_xlate.py (patches 0005-0011 are ours; the Linux note kept), totk.ini.example (both sections). The contact pass
release went into gfx_present.c, the shared half of the old gfx_window.c.
aniso defaults to game: the picture stays as before until a player raises it in the menu.

The value is now a count (1 still means 16, capped at 4096), so blocks such as the deferred lighting shaders' camera
block, whose shadow cascade matrices sit at vec4 42 to 58, can be read from a frame dump.

Shared runtime code now goes through runtime/platform/platform.h, implemented by platform/win32.c and a new
platform/linux.c: futex locks, a userfaultfd and PAGEMAP_SCAN write watch, signal-based async preemption, our own
fiber switch, and a SIGSEGV handler for the thaw and crash hooks. The window, input, menu and software keyboard get
SDL3 back ends beside the Win32 ones, with the swapchain (gfx_present.c) and input merging (input.c) shared. SHA-256
replaces BCrypt, ELF builds get their own override sections, and the build tools gain Linux branches.
On Linux the selftest and the gfx-abi, astc, nvn and window probes pass. probe-vkmem still fails: imported guest
memory cannot be write-watched on Linux, which the shadow buffers in vk_memory.c will address.
Imported pools put vertices, indices, constants and storage buffers in system memory, so discrete GPUs read them over
PCIe on every draw. A pool now gets a device-local mirror on its first use as a vertex, index, uniform, storage or
indirect buffer; bindings, buffer copies, fills and uniform updates use it at the same offsets. The first access of a
submission syncs the pages written since (write-watch snapshots shared with the texture checks, plus
nvnMemoryPoolFlushMappedRange ranges) in a prologue command buffer before the part; what the GPU writes into a mirror
goes back to guest memory at the end of the submission. TOTK_MEMORY=import|mirror|verify overrides the device class;
verify compares sampled mirror pages with guest memory at the fence. The vkexec probe gains a mirror part.
