* feat(libkernel): implement sceKernelReleaseFlexibleMemory
Unmaps the range through sceKernelMunmap, which returns its pages to
the flexible memory budget, as fpPS4 and prosper do.

* test(libkernel): keep the flexible memory release check apart from the batch map checks

Both take the FreeBSD msghdr (48 bytes, iovecs of a pointer and a 64-bit
length) and run on the host sockets: sendmsg gathers the iovecs and sends
through sendto, recvmsg receives into one buffer and scatters it. A
datagram longer than the iovecs is cut and reported with MSG_TRUNC, also
on Windows where recvfrom fails with WSAEMSGSIZE. More than 1024 iovecs
fail with EMSGSIZE. No ancillary data is ever received, so recvmsg
clears msg_controllen; sending control data throws.

NH6xARDOVv8 is the NID of sceKernelGetOperationMode. PPSA12544 passes two
int outputs and logs them as mode and submode; both are reported as 0.
B2n8aDorSH4 and PZQhiiLXRFs are sceKernelSyncOnAddressWait32 and
sceKernelSyncOnAddressWait64, implemented by #633, and are no longer added
as unimplemented exports.

Implement scePthreadGetschedparam and scePthreadSetschedparam on top of
the thread priority, POSIX utimes and fsync on top of sceKernelUtimes
and sceKernelFsync, and sceUserServiceGetAccessibilityZoomFollowFocus
like the other accessibility queries. Add the remaining imports of
PPSA12544 as unimplemented exports and record unknown NIDs and
signatures in the technical debt.

Sign-in, web browser and player dialogs finish cancelled; the message dialog finishes at once;
NpAuth, entitlement consumption, reachability, account age and the NpUtility bandwidth test
report signed out; sceKernelMtypeprotect changes the protection (the memory type has no host
equivalent); the APR ForEach resolvers resolve every path and report each failure in its own
result entry. vswprintf's stub is dropped in favor of the existing wide-formatter
implementation, which already covers it on every platform.

libkernel:
- direct memory keeps its contents per physical page across unmap and
remap; a page mapped at two live addresses at once throws
- sceKernelDirectMemoryQuery answers from tracked allocations
- SCE protections read back as set, GPU and AMPR bits included
- APR prefix path resolve, file size and stat by id, positional reads,
fsync/pread/pwrite; directories open as descriptors on Windows
- sceKernelCheckReachability, getpeername, shutdown
- Dinkumware C11 threads (_Mtx_*, _Cnd_*, _Thrd_*) in the title libc
layout; any pthread stack size, rounded at thread creation
libc:
- unaddressed guest mappings go to the system-managed area from
0x2_0000_0000, leaving the application area to fixed mappings
- the process starts in /app0
- guest sscanf on Windows; a null %s prints as (null) as on FreeBSD
- localeconv, _FNan, _FDtest, _FExp, __udivti3, wcsncpy_s, aligned
operator new, _Throw_Cpp_error
Tests: direct memory following physical pages, guest formatting.

- libc: reserve guest memory in one arena below the PS5 map limit with
MEM_WRITE_WATCH (GuestArena) and a caching guest heap; the allocation
registry gains a generation counter, an invalidator callback for the
driver's page cache and a pin waiter for leased ranges. This replaces
the fault-based GuestMemoryTracking/GuestMemoryBacking layer, whose
files are removed.
- libkernel: mmap/mprotect/munmap on the arena, flexible memory budget,
real sceKernelVirtualQuery; POSIX pthread layer, rwlocks, timed locks,
TSD, event flags; 0.5 ms scheduler tick and high-resolution sleeps;
TSC/clock/time functions; file APIs return SCE errno codes; the APR
file-streaming API.
- libc: vectored crash reporter with backtraces for fatal exceptions,
SIGABRT, UCRT invalid parameters and process exit; SSE4a EXTRQ/INSERTQ
emulation for Intel hosts; %ls/%lc/%S/%C with the guest's 16-bit
wchar_t; hand-written setjmp/longjmp for the guest jmp_buf; a path
alias table for short save-data mount points; more string, stdio and
math exports.
