ReadHeader reads fields up to offset 0x40 but only rejected files
shorter than 20 bytes, so a truncated ELF failed with
"FileByteOffset out of bounds" instead of "File too small for ELF header".

Lower INSERTQ xmm1, xmm2 (F2 0F 79) out of line with SSE2 only instead of
failing the --to-intel relink. Length and index are read from bits 69:64
and 77:72 of the source; dst[127:64] is zeroed as on hardware.

Only the lines this branch added lose their comments; the commits before
keep them, with the reasoning behind each change, for whoever digs into
that code later.

- --exclude-sce-module <file> (repeatable) drops one title module from
guest conversion, e.g. a title libc.prx, while the rest of sce_module
is still relinked as guest modules
- the instruction scanner stops at zero padding that ends a code segment
with an odd byte instead of failing on a truncated `add [rax], al`

The project's coding conventions restrict inline comments to
technical-debt markers, #endif, and namespace-close trailers. Remove
the explanatory comment on writeGotStub's DIR64 write; the same
rationale (why the slot must hold the preferred-VA form, and why the
base-relocation pass was moved after lazy-stub writes) is already
captured in the fix(relinker) commit message and PR description.

The Windows PE lazy-import GOT slot was written as a bare 4-byte RVA,
but the .reloc entries generated for the .gtls/data sections use
IMAGE_REL_BASED_DIR64, which only adds the load delta to whatever is
already stored at the slot. A bare RVA therefore resolved at runtime
to (loadBase - ImageBase + rva) instead of the intended stub address,
pointing into unmapped memory whenever the module was not loaded at
its preferred base.
Write the full 8-byte preferred-VA form (ImageBase + stubRva) instead,
matching DIR64 semantics, and generate a base relocation entry for
each lazy-stub GOT slot. The .reloc section is now built after the
lazy stubs are written into their target sections rather than before,
since it previously captured only the relocations known at that
point and missed the newly patched slots entirely.
Resolve conflicts with boykopovar/AnyPS5#10 (sce module loading) and
later upstream changes.
- Pthread Cond/Mutex: take upstream. It already releases mutex
ownership across condition waits, returns ETIMEDOUT 0x8002003C, and
rejects unlocks from non-owners for every mutex type.
- Pthread Thread: keep upstream's lifecycle, Windows adoption and job
affinity; re-apply the POSIX fixes on top: reference-counted
release on join/detach/exit, self-join rejection on both platforms,
and scePthreadSelf adoption for threads not created by
scePthreadCreate.
- Semaphore: keep upstream's TimedWait::Condition and wait tracing;
re-apply sceKernelDeleteSema waking waiters with EACCES.
- Relinker: keep --windows-gui alongside upstream's --skip-sce-module,
trampoline-aware Patch signature and new Python tests.

feat(relinker): lower register-form EXTRQ and relocate following instructions for short sites
- **Lowering:** register-form EXTRQ is emitted out of line with SSE2 only. Two scratch XMM registers (distinct from both operands) are spilled; one gets the index (`src >> 8 & 63`), the other `(64 - length) & 63` (`length` masked to 6 bits, so 0 means 64). The destination is shifted right by the index, then left and right by the complement, which keeps the low `length` bits. INSERTQ register form is still reported as unsupported.
- **Short sites:** when a site is shorter than a `jmp rel32`, the converter extends it over the instructions that follow it until it's 5 bytes long:
- following EXTRQ/INSERTQ instructions (before any other instruction) are lowered into the same stub, via a new `MatchSequence`;
- other instructions are copied after the lowered body (`LowerOutOfLine`'s new `trailing` bytes), but only if they're sequential, have no RIP-relative operand and no branch target;
- anything else (a return, a branch, RIP-relative code, the segment ending) still fails the relink, as does a branch target inside the extended site.
- `docs/TechnicalDebt.md` now lists only the INSERTQ register form, MONITORX/MWAITX/CLZERO/RDPRU/MCOMMIT and SHA-NI.
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.

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.

std::system returns a wait status on POSIX, so returning it from main
truncated a guest exit code of 1 (status 256) to 0. The prompt also
required pressing Enter twice because cin.get followed cin.ignore.

EXTRQ, INSERTQ, MOVNTSS and MOVNTSD are rewritten at relink time: same-length in-place forms
where they exist, otherwise a jmp rel32 into an appended executable section holding a
scratch-free SSE body and a jump back, so no code shifts and no RIP-relative or jump-table
operand needs adjusting. Decoder fixes for POPCNT and 0F BB (BTC), codegen and elfpatcher
tests, README and technical-debt notes. The runtime illegal-instruction trap stays as a
fallback.
