A host thread adds each second in which the window has the focus and the game presents frames, keeps the total in
<profile>/playtime.txt (every 30 s and at exit) and the Game tab of the settings menu shows it with this run's share.

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.
A player who starts totk.exe from Explorer or a shortcut had no log to attach to a report: the log went only to stderr.
A game run whose stderr is not a file (a console or a pipe) now also writes logs\totk.log, keeps the four earlier
runs as totk.1.log to totk.4.log, and stops the file at 64 MiB. Runs whose stderr is a file (run_game.py, 2> file) and
the tool modes write no extra file. Lines from before the file opens (mem_init comes first so the CRT heap stays out of
the guest address space) wait in a static buffer.
Crash reports, fatal errors, IPC and SVC diagnostics, guest debug output and the boot: lines now go through
rt_logf / rt_log_raw, so they reach the file too. Open log folder in the menu opens the folder of the file.

The game's Commit returns at once. Every later change to the working copy, Unmount and the next Commit wait for the thread, so no write lands in the snapshot, and the window close, guest ExitProcess and --frames exits wait through fs_save_flush. A crash during the commit loses that commit only; the transaction and save_recover are unchanged. probe-fs waits for each commit and checks a write and an Unmount right after Commit.
