The scaffold, list_wpf_components, get_wpf_api_reference and search_wpf_api showed package IDs in lowercase (infragistics.wpf.datagrids.trial), because build-api.ts took them from the nuget/packages folder names. Agents copied that casing into users' .csproj files.

• scripts/build-api.ts: reads the ID from each package's .nuspec <id> (e.g. Infragistics.WPF.DataGrids.Trial). The build fails if the .nuspec is missing or its ID doesn't match the folder. This also covers dependency-only packages that aren't listed in WpfDocs.csproj (e.g. Barcodes, CalculationManager). EXCLUDE_PACKAGES is now compared without case.
• scripts/validate-package.ts: fails if namespaces.json has lowercase IDs again.
• scripts/smoke-test.ts: checks that the scaffold prints dotnet add package Infragistics.WPF.DataGrids.Trial. It runs for both servers.

Verified

After npm run build:all, the casing is the only change in the data: 191 components, 6,907 search entries and 6,907 API files, the same as before, and XamXGrid is still excluded. npm run test:dotnet, npm test and npm run typecheck pass.
