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.
