Replace the system work queue's SYS_INIT (POST_KERNEL) with a K_KERNEL_INIT_POST() hook. The init function and its hook entry live in this translation unit, which is linked only when something references the system work queue (e.g. k_sys_work_q), so an image that never uses it neither links this code nor runs this init -- the same pay-per-use behavior SYS_INIT gave, now without the init level/priority. The hook runs before POST_KERNEL device init so that drivers initialized there may submit work to the queue. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Anas Nashif <anas.nashif@intel.com>
