logd now writes all log output to /var/log/system.log (5MB auto-rotation) in addition to existing scheme listeners. Falls back to /tmp/logd-fallback.log if /var/log is unavailable. Logs survive reboots for post-mortem analysis. Part of Phase A2 (Boot Reliability) from BOOT-PROCESS-AUDIT-2026-05-03.
