dpg-gauges

Dear PyGui gauge widgets for dashboards and telemetry displays.

Current implementation status: Step 5 first catalogue rendering is implemented. Analog, digital, bar, level, status, segmented, compass, thermometer, battery, and multi-value gauges render Dear PyGui drawlist visuals. Bar/level gauges draw threshold bands and markers; analog gauges draw ticks, redline bands, markers, and needles.

Runtime value updates are intended for the Dear PyGui GUI thread. Attached gauges redraw immediately for simple value/configuration changes.
