MerijnandClaude Opus 5.5 51b6079b5b fix(libkernel): no allocation while the target is suspended; own the wait count ...

The APC delivery was allocated after SuspendThread, so a target holding
the allocator lock deadlocked the raising thread; it is now allocated
before the suspend. The wait count a raise checks lived in the target's
thread_local storage and dangled once the thread exited; it is now a
member of PthreadPrivate, which TimedWait counts into through a
thread-local pointer bound when the thread starts, and a raise on a
thread that already finished returns ESRCH. TechnicalDebt gets one line
per unverified choice: Windows only, the FreeBSD ucontext layout, the
signal mask, the YMM upper halves, and delivery to threads outside
TimedWait.

AI-assisted: yes
