chore: organize solution into module folders (Core/Server/Drivers/Client/Tooling)
Group all 69 projects into category subfolders under src/ and tests/ so the Rider Solution Explorer mirrors the module structure. Folders: Core, Server, Drivers (with a nested Driver CLIs subfolder), Client, Tooling. - Move every project folder on disk with git mv (history preserved as renames). - Recompute relative paths in 57 .csproj files: cross-category ProjectReferences, the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external mxaccessgw refs in Driver.Galaxy and its test project. - Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders. - Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL, integration, install). Build green (0 errors); unit tests pass. Docs left for a separate pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
