[AndreaF-UniBO]

What changed

• renames and upgrades the desktop application to PyWALL v13 (0.13.0)
• removes the historical Segmentazione DL interface and TopoMortar/Ultralytics runtime
• uses only Meta's official SAM 2 backend with an explicit, checksum-verified checkpoint download
• adds reproducible Windows setup, launch and test scripts
• adds a current application screenshot and release documentation
• excludes the virtual environment, model weights and six photographs whose redistribution rights are undocumented

Validation

• public-source suite: 10 passed, 2 expected skips
• release-candidate suite with official SAM 2: 11 passed, 1 expected sample-assets skip
• user confirmed the local interactive application works correctly
• pip check, source compilation, PNG/DXF export smoke tests and secret/large-file scans passed

Impact

This replaces the v0.1.0 application on the default branch while preserving the repository history. The v0.13.0 source remains an alpha research-software release and requires expert review of segmentation outputs.
