feat: Docker images, RVF export, and README update

- Add docker/ folder with Dockerfile.rust (132MB), Dockerfile.python (569MB),
  and docker-compose.yml
- Remove stale root-level Dockerfile and docker-compose files
- Implement --export-rvf CLI flag for standalone RVF package generation
- Generate wifi-densepose-v1.rvf (13KB) with model weights, vital config,
  SONA profile, and training provenance
- Update README with Docker pull/run commands and RVF export instructions
- Update test count to 542+ and fix Docker port mappings
- Reply to issues #43, #44, #45 with Docker/RVF availability

 ### Using Docker
 
+Pre-built images are published on Docker Hub:
+
 ```bash
+# Rust sensing server (132 MB — recommended)
 docker pull ruvnet/wifi-densepose:latest
-docker run -p 8000:8000 ruvnet/wifi-densepose:latest
+docker run -p 3000:3000 -p 3001:3001 -p 5005:5005/udp ruvnet/wifi-densepose:latest
+
+# Python sensing pipeline (569 MB)
+docker pull ruvnet/wifi-densepose:python
+docker run -p 8765:8765 -p 8080:8080 ruvnet/wifi-densepose:python
+
+# Or use docker-compose for both
+cd docker && docker compose up
+```
