fix(systemd): add MemoryMax=24G circuit breaker to prevent segfault crashes
The server has a memory leak (~2.5 GB/h) that eventually triggers a Bun
runtime segfault. These cgroup limits turn the uncontrolled crash into a
controlled OOM-kill → clean restart via Restart=on-failure.
MemoryHigh=20G (soft throttle) + MemoryMax=24G (hard cap).
Machine has 33.24 GB total; 24G leaves OS headroom.
