v0.4+v0.5: TUI dashboard, tab completion, systemd, Docker, process isolation

- New: services/sysmon_widget.py (CPU/MEM/DISK/NET real-time) - Enhanced: tui_service.py (4-section layout, plugin status panel) - Enhanced: command_service.py + tui (Tab completion) - New: deploy/sensu.service (systemd) - New: deploy/Dockerfile (Alpine, 4200+4240) - New: services/process_isolated.py (multiprocess plugin isolation) - Tests: 23/23 passing
