First public release.

Breaking changes vs internal version:

• Requires sheet_config.json (copy from sheet_config.example.json). All hardware lists, worksheet name, and column map are now in the config — no code edits needed to adapt to a different spreadsheet.

Bug fixes:

• Crash on submit (missing inp_tester attribute)
• row = 2 overwrite bug when serial not found in sheet
• GPU matching broken for "NVIDIA RTX: 3060" format vs WMI names
• SSD size detection wrong for 180 GB and 240 GB (GiB vs GB mismatch)
• net accounts always reported "reset" regardless of admin rights
• "Colors" check result was never written to the sheet
• Rescan did not switch to the loading screen

Improvements:

• Split into config.py, scanner.py, sheet_manager.py, tester.py
• Brand aliases (e.g. "Hewlett-Packard" → "HP") in config
• AMD Ryzen name normalisation ("Ryzen 5" → "R5")
• tools/ third-party binaries gitignored; tools/README.md lists download links
