docs(libkernel): credit only OpenAGC with the sceKernelHasTrinityMode test
...
Backport's FINDINGS.md says sceKernelHasTrinityMode reads
hw.sce_main_socid; the masked comparison with 0x840fc0 it states is for
sceKernelIsTrinityMode. Only OpenAGC gives that comparison for
sceKernelHasTrinityMode, so the debt entry now credits Backport with the
sysctl read alone.

feat(libkernel): implement sceKernelHasTrinityMode for a base PS5
...
sceKernelHasTrinityMode returns 0, the answer of a base PS5, as
sceKernelIsTrinityMode already does. Two public readings of firmware
libkernel (OpenAGC for 11.60, Backport for 11.00 to 12.70) say it
compares hw.sce_main_socid with its low five bits cleared against
0x840fc0; the base PS5 SoC id recorded for sceKernelGetMainSocId,
0x840f80, fails that test. The prototype int (void) comes from the 23
calls in a UE5 title, each storing setne of the result in a guarded
static with no argument set up.
Titles import it from libkernel, but only the libkernel_sys placeholder
inventory exported it, as a throwing stub. The export moves to libkernel
next to sceKernelIsTrinityMode, and the inventory and its counts drop
the entry. guest_operation_mode checks the result.

fix(libkernel): spin and yield when a condition variable wait relocks its mutex
...
FreeBSD 11.4's _mutex_cv_lock takes the mutex back through
mutex_lock_common, so a woken waiter tries once, spins and yields by
the mutex's counts before it blocks. The wait here called the native
lock directly; it now goes through the same spin and yield path as
scePthreadMutexLock.

sched_getparam, sched_getscheduler and sched_setparam with the own pid
from a thread other than the main thread act on the main thread once it
has registered through scePthreadSelf, as FreeBSD's p1003_1b.c selects
the first thread. Before registration, after the main thread exits and
on macOS they still throw.

MihawkOS (PPSA99170) reads sysctl {1, 14, 8, 0} while it starts and the
runtime throws on the unsupported MIB, which aborts the title.
KERN_PROC_PROC takes no pid, so the node lists the one guest process the
runtime hosts, as the same kinfo_proc kern.proc.pid already builds.

docs(libkernel): sysctlnametomib returns ENOENT for kern.smp.maxcpus, kern.stackprot, kern.sched.name and kern.timecounter.hardware
...
Old claim (entry 155 of docs/dev/debt/libkernel.md, second half): sysctlnametomib still throws for these four names.
What the code does: these names are only in IsUnansweredName, which the read path of sysctl uses. sysctlnametomib does not match them in TopLevelNode, its known-name table or its SystemStrings and SystemIntegers tables, so it reaches the final fall-through, sets errno to 2 (ENOENT) and returns -1 without throwing.

fix(libkernel): spin and yield by the mutex spin and yield loop counts
...
Lock and timed lock now try the mutex up to the spin count with a pause
between tries, then up to the yield count with a yield before each try,
before they block, as FreeBSD 11.4's mutex_lock_sleep does. Trylock and
a lock the thread already holds do not spin. A uniprocessor host skips
the spins and keeps the yields.
