Lindamea1andClaude Opus 5.5 3237083172 fix(libkernel): return ESRCH from scePthreadAttrGet for a thread that has ended ...

scePthreadAttrGet copied the attributes of any non-null handle, so a
thread that was joined or had finished still answered 0, and a thread
that ended detached was read after its object had been freed. FreeBSD
11.4's _pthread_attr_get_np returns ESRCH for a dead or reclaimed thread,
and Monster Hunter Wilds (PPSA24191) reuses a slot of its thread table
only when scePthreadAttrGet returns 0x80020003.

After the EINVAL checks it now returns ESRCH unless the handle is a live
guest thread, and copies the fields while holding the thread registry
lock (LockLiveGuestThread), so a detached thread exiting during the call
is not freed under the copy. GuestThreadIsLive uses the same lookup.
pthread_attr_get_np, which the title does not import, is left as it is;
the debt entry records the difference.
