MaxandClaude Opus 5.5 3ddaa64707 fix(libkernel): return EINVAL for the semaphore arguments the console rejects 
The prosper console oracle measured SCE_KERNEL_ERROR_EINVAL for creating
a semaphore with an initial count above the maximum, a maximum of 0, a
negative initial count or a null name, for polling 0 or more than the
maximum, and for signalling 0. These threw, or polled past the maximum
returned EBUSY, and signalling 0 succeeded.
