devilismyfriend f3ac61000d feat(runtime): guest arena, kernel thread/sync/file APIs, crash hooks
- 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.
