- Connector tab: host/port fields, connect/disconnect button, status
- Dashboard tab: live QTreeWidget of the full snapshot hierarchy;
physical values show value and unit in separate columns;
expand state preserved across refreshes
- Plot tab: matplotlib time-series subplots (2 columns) for every
physical {value, unit} field, scrollable, auto-layout on new keys
- TcpReader runs in a daemon thread and delivers messages via
Qt signals so the UI never blocks
