demos: add ArcGIS Pro live-bridge demo (registered arcgis-pro harness)

Add a Real-World Demos entry for the arcgis-pro harness (listed in
public_registry.json, merged in #318): an agent driving a live ArcGIS Pro
session over the MCP bridge — read project, zoom to layers, run GP, export
layouts. GIF (860px/15fps, 3.3MB) generated from the local demo video with
the standard ffmpeg palette workflow.

+### ArcGIS Pro — Live Agent Cartography via the MCP Bridge
+
+> **Harness:** [`arcgis-pro`](https://github.com/Jasper0122/CLI-Anything-Arcgis-Pro) (registered in [`public_registry.json`](public_registry.json)) | **Mode:** live-Pro MCP bridge | **Artifact:** Agent-driven map navigation in a running ArcGIS Pro session
+
+An agent drives a **live, open ArcGIS Pro session** through an MCP bridge — reading the project, zooming the map to feature layers, running geoprocessing, and exporting layouts — while each step executes inside Pro as you watch. ArcGIS Pro is Esri's commercial GIS desktop (Windows-only, licensed), so this wraps its official **ArcPy / ArcGIS Pro SDK** rather than being generated from source — the ArcGIS Pro counterpart to the QGIS harness.
