fix(recompiler): widen constants of 64-bit operands instead of repeating them
TranslationContext::readU32Pair builds a 64-bit source from two 32-bit reads, taking the high half from offsetOperand(operand, 1). For registers that is the next register. For a literal or an inline constant, offsetOperand returns the same operand, so the constant ended up in both halves: the literal L was read as L:L instead of 0:L.
feat(libc): sscanf_s on linux
sscanf_s was a NotImplemented placeholder in libc/Export.cpp, and a retail title uses it to parse strings. It's now implemented on Linux. Windows still throws NotImplemented.
feat(agc): emit indexed indirect draws
This implements `sceAgcDcbDrawIndexIndirect` and `sceAgcDcbDrawIndexIndirectMulti`. They were stubs that aborted with "not implemented".
They follow the existing non-indexed `sceAgcDcbDrawIndirect` / `DrawIndirectMulti`:
- `DrawIndexIndirect` emits `DRAW_INDEX_INDIRECT` (0x25): data offset, base vertex / start instance SGPR locations, draw initiator (5 dwords, matching `GetSize` = 20).
- `DrawIndexIndirectMulti` emits `DRAW_INDEX_INDIRECT_MULTI` (0x38): the same fields, plus the draw-index location / count-indirect control word, count, count address and stride (10 dwords, matching `GetSize` = 40). The stride must be at least 20, the size of an indexed record.
fix: support SDK startup, linear framebuffers and indexed draws
Fix SDK startup with an empty allocator replacement table, add linear framebuffer presentation through the current presentation path, and implement explicit indexed draws with packet validation. Retain buffer-address regression coverage for the correction already upstream, and restrict the POSIX exception-runtime test to Unix so Windows test builds succeed.
Also fix two issues reproduced after rebasing: render-target format lookup probed unsupported formats by repeatedly throwing exceptions, costing about 78 ms per draw; the lookup now searches supported entries directly. Recorder buffers now use Windows FLS cleanup to avoid MinGW freeing emulated TLS storage before running their destructors. Cross-DLL tests check independent values and destruction on standard and native Windows threads.
GuestModuleWriter::WriteLinux adds read permission to every PT_LOAD, including
the SCE dynlib data segment, which has no flags and is never mapped on the PS5.
When that segment starts inside the last page of the preceding RW segment, the
read-only mapping covers the tail of its bss and the module's initializer faults
on its first write there. The symbol and relocation tables it holds are already
copied into the appended segment, so it no longer needs to be mapped.

The host-region fallback added with the Demon's Souls work calls VirtualQuery and
includes windows.h unconditionally, so libkernel no longer compiles on Linux.
On Linux, read the containing mapping and its permissions from /proc/self/maps.

Every lock, unlock, signal and wait took the process-wide initialisation
mutex to read the handle, serialising all guest synchronisation. The
handle is now read atomically and the lock is only taken to initialise a
static initializer or to report a destroyed object.

The merge brought a NotImplemented scePthreadOnce_nid_postfix next to the
existing scePthreadOnce. The NID patcher gives the NID to the postfixed
symbol, so the stub replaced the working export and the title aborted at
its first once-initialisation.

When the presentation device was replaced, textures created on the old
device stayed in the global sampled and storage texture caches and kept a
reference to the destroyed TextureDetiler, whose VkDevice was then read
corrupted ("missing Vulkan function: vkResetDescriptorPool" at startup).
The replacement now flushes the old device's cached storage textures and
publishes every unit shadow before waiting for the device, and the device
teardown erases the cache entries that belong to it.

Brings in main up to 9958d26 (homebrew runtime, POSIX wrappers in
libkernel, sce_module guest modules and --skip-sce-module, the --to-intel
general pipeline, libSceRandom, libSceRtc, libScePosixForWebKit,
libRenoirCore, test wiring).
Resolutions where both sides implemented the same thing:
- libkernel pthread: main's structure (lazy static initialisation,
destroyed markers, MutexOperations/CondOperations, mutex protocol and
condattr clock) with this branch's TimedWait deadlines and condition
(precise timed lock/wait on Windows), wait tracing, the adaptive mutex
type 4, POSIX default ERRORCHECK mutexes, EDEADLK/EPERM results instead
of throws, and condition clocks honoured for absolute timeouts.
- libc locale: the guest Dinkumware ABI (_Locimp, facet vtables, short
ctype/case tables, locale ids, stream storage) is kept because guest code
inlines those layouts; main's C character functions are kept on top.
- libc stdio/strings/math: main's stream functions (guest FILE status
sync), strerror/perror, remove, formatting, string and math exports win
over this branch's duplicates.
- libc paths: main's working directory with this branch's path aliases
resolved on the normalised guest path.
- libkernel file: this branch's sceKernel* results as SCE errors, main's
POSIX wrappers and both fstat helpers.
- relinker: this branch's stub lowering keeps its trampolines through the
main executable path; guest modules refuse lowerings that need stubs.
- AGC driver: main's rendering wait is executed by this branch's workers.

sceAgcDcbDrawIndexIndirect and sceAgcDcbDrawIndexIndirectMulti emit
DRAW_INDEX_INDIRECT (0x25) and DRAW_INDEX_INDIRECT_MULTI (0x38) like their
non-indexed counterparts, with 20-byte records.

readU32Pair read a literal or inline constant into both halves of a 64-bit
source. A literal is now zero-extended, an integer inline constant
sign-extended and a float inline constant becomes the matching double.

progress.py stores the names of implemented and pending items, can
measure another source tree with --root and prints a Markdown diff of
two runs with --compare. The Progress report workflow compares every
pull request with its base, and Progress comment posts the result as a
single comment, updated on every push and removed when progress no
longer changes. Commenting runs as a separate workflow_run so pull
requests from forks never run with write permissions.

tools/progress.py counts implemented prx functions and RDNA instructions
recognized by the shader recompiler, and renders treemaps, badges and an
index page. The Progress workflow deploys them to GitHub Pages on every
push to main, so nothing generated is committed to the repository.

Convert 5 remaining pure stubs (log + return 0) to throwing with
literal NID, keep trailing return 0. Real SDL/state-tracking impls
(20 studio + 2 libfmod + C++ classes) untouched. Remove stale
logging-stub comments only around touched stubs.
Throwing: Cm2cmtCv8cA, EfM9xXvBmxk, Js90KQXVS4s, oCYWES02VPc, vVwA2cZA5e4
