* launcher: add minimize and maximize buttons to the main window
The main window is a QDialog, which on Windows only gets a close button.
* graphics: keep the game's aspect ratio when presenting to the window
The guest frame was blitted across the whole swapchain image, so a window
or fullscreen display whose shape differs from the frame stretched the
picture. Fit the frame inside the window instead and clear the remaining
bars to black. The video-out overlay layer is drawn into the same
rectangle so it stays aligned with the frame underneath.
* launcher: accept custom screen resolutions such as 21:9
The resolution was a fixed enum of four 16:9 sizes. Make the combo box
editable so any WIDTHxHEIGHT between 320 and 16384 can be entered, and
add ultrawide presets (2560x1080, 3440x1440, 3840x1600, 5120x2160).
Settings saved by older launchers stored the enum key ("R1920X1080");
NormalizeResolution still accepts that form, so they load unchanged.
* launcher: add a Stretch to window option
Presentation now keeps the game's aspect ratio with black bars. Add
--stretch to fill the whole window as before, exposed in the launcher as
a "Stretch to window" checkbox under General, off by default.
* launcher: make the settings dialog resizable and its tabs scrollable
The dialog had no maximize button and pinned its minimum width to its
initial 900 px, and without scroll areas it could not be made shorter
than its content. Add a maximize button (not minimize, since the dialog
is modal), drop the width pin, and wrap each tab page in a frameless
scroll area.
With the scroll areas the layout's minimum size no longer forces the
dialog open, so size it explicitly: grow it to fit the largest tab,
capped at the available screen, when there is no saved geometry and
whenever the global settings add the game folders panel.
* launcher: simplify display options and preserve saved settings

Performance changes from #1495:
- Sync changed BDA ranges instead of scanning all mappings.
- Let VMA suballocate BDA buffers.
- Remove the renderer lock from presentation.
- Keep compatible pipeline caches across builds.
- Fold masked shifts that always produce zero.
* Add `stretch to window` support
* Address comment
* Allow window resizing by default and recreate swapchain on resize

* macos: POSIX platform layer (host fault handler, virtual memory)
- hostException: Mach/POSIX signal-based host fault handler mirroring the
Windows vectored handler (SIGSEGV/SIGBUS/SIGILL), behind
'#elif defined(__APPLE__)'. Windows and Linux branches are untouched.
- sysLinuxVirtual: mach_vm_region-based is_mapped (no /proc/self/maps on
macOS), PTHREAD_MUTEX_NORMAL, and a MAP_FIXED carve-in-place allocator that
never leaves an unmapped hole for dyld/Rosetta/Metal to claim. All
__APPLE__-guarded; the original Linux allocator path is preserved verbatim.
- sysLinuxDbg/sysLinuxFileIO: libgen.h for basename(), and a POSIX
opendir/readdir implementation of SysFileGetDents (previously a stub).
* macos: guest kernel backing, threads, and POSIX libs
- memory/memoryAddressSpace: anonymous shm_open backing (macOS has no
memfd_create) and re-reserve-on-unmap so a guest MAP_FIXED remap never
destroys a host mapping (__APPLE__-guarded). Drops host <sys/mman.h> MAP_*
macros so the guest's constexpr MAP_* constants compile (no-op on Windows).
- pthread: undef the host PTHREAD_STACK_MIN macro; on non-Windows, pin the
stack-switch asm's guest rsp/rbp to callee-saved r14/r15 (the template
clobbers r12/r13); __APPLE__ no-op for the absent pthread_condattr_setclock.
The Windows stack-switch asm is byte-identical.
- network: define SOCKET/INVALID_SOCKET for the non-Windows paths (were
undefined at 20+ use sites), and rename the non-Windows kernel_clock_*
helpers to the CamelCase names the callers already use. Both repair the
shared non-Windows build. Integer reinterpret_cast -> static_cast.
* loader: pin stack-switch asm operands to callee-saved registers
RunEntry switches to the guest stack with an asm template that clobbers
r12/r13 before consuming its inputs. With plain "r" constraints the compiler
may place func/guest_rsp/guest_rbp into r12/r13, so 'callq *func' jumps
through the saved host rsp -- a latent miscompile on every platform that any
unrelated codegen change can trigger. Pin the inputs to rbx/r14/r15, which the
template never touches and the SysV callee preserves.
General correctness fix (not macOS-specific); the same fix is applied to
pthread RunOnGuestStack.
* macos: Vulkan/MoltenVK graphics enablement
- pageManager: GPU write-tracking via Mach VM queries + mprotect (mprotect
cannot report the previous protection, so the expected-old check is dropped),
thread id via pthread_mach_thread_np, 4 KB page-size check -- __APPLE__-guarded.
- shaders/renderDraw/vulkanWindow: MoltenVK lacks VK_EXT_color_write_enable,
VK_EXT_depth_clip_enable and depthBounds; fall back to static color-write
masks and default depth clipping, request VK_KHR_portability_subset, and
reuse the graphics queue for present when only one queue is exposed. Non-Apple
pipeline/extension setup is unchanged.
- window: optional borderless window (KYTY_BORDERLESS) to sidestep a Rosetta
NSException in macOS window chrome.
* graphics: macOS thread identity for region tracking
Region-ownership locks resolve the current thread via GetCurrentThreadId()
on Windows and EXIT elsewhere. Use the Mach thread port on macOS (nonzero
per-thread id; 0 stays the no-owner sentinel).
* macos: marshal AppKit window operations to the main thread
The present worker thread shows the window, updates its icon and title, and
recreates a lost Vulkan surface. AppKit traps with 'Must only be used from the
main thread' when these run off the main thread. Route them through a small
task queue drained by the SDL main loop (an SDL_USEREVENT wakes the loop when
it is blocked in SDL_WaitEvent). Title updates are fire-and-forget; showing
the window and surface recreation wait for completion.
Windows and Linux call the SDL functions directly, as before.
* build: ignore the _Build output directory
_Build is the conventional out-of-tree build location (only _Build/vscode-clang
was ignored); a stray git add could sweep build artifacts into a commit.
* macos: isolate stack-switch workaround
