- SYSCALL_SETITIMER = 92, SYSCALL_GETITIMER = 93
- ITIMER_REAL: uses alarm queue with repeating interval
- ITIMER_VIRTUAL: decrements on user-mode ticks, sends SIGVTALRM
- ITIMER_PROF: decrements on user+kernel ticks, sends SIGPROF
- Scheduler tick logic was already in place
- 35/35 smoke tests pass, cppcheck clean
