Release v1.3.0: STAMP pipeline, FedProx, Duke benchmark, CI/CD

[Ultimate-Storm]

Summary

• Bump odelia_image.version from 1.2.0 → 1.3.0
• Add comprehensive CHANGELOG.md documenting all v1.3.0 features

This PR should be merged after all feature PRs (#252–#259) are merged into main.

v1.3.0 Release Highlights

🔬 STAMP Classification Pipeline

• Separate Dockerfile_STAMP for KatherLab STAMP 2.4.0 (Python 3.11, PyTorch 2.7.1)
• buildDockerImageAndStartupKits.sh accepts -d flag to select Dockerfile
• Synthetic STAMP dataset generator for integration testing
• STAMP integration tests: preflight check, local training, simulation mode
• Per-round metrics CSV callback (STAMPMetricsCallback) for training monitoring

🔄 FedProx Aggregation Strategy

• FedProxCallback adds proximal term (μ/2) × ‖w_local − w_global‖²
• Compatible with both ODELIA and STAMP pipelines
• Configurable via FEDPROX_MU environment variable
• Documented comparison of FedAvg, FedProx, Scaffold, and FedOpt

🧪 CI/CD for STAMP

• Unit tests for stamp_training.py, stamp_model_wrapper.py, fedprox_callback.py
• STAMP integration tests in pr-test.yaml
• Unified lightning package for cross-pipeline compatibility

📊 Duke Benchmark Pipeline

• run_duke_benchmark.sh orchestrates build → deploy → train → collect → compare
• deploy_and_test.sh reads SITES/SERVER_NAME from deploy_sites.conf
• deploy_sites.conf.example with dl0/dl2/dl3 templates

📐 Architecture Documentation

• Expanded README with Mermaid diagrams (system architecture + training pipeline)
• Supported pipelines comparison table
• Project structure overview

🔐 Differential Privacy Assessment

• Gap analysis of current PercentilePrivacy vs formal (ε,δ)-DP
• Opacus/DP-SGD roadmap for v1.4.0
