Summary

• Rename the RAG tool to search_documents for clearer tool-calling behavior.
• Fix data source deletion so cleanup is complete: vector embeddings + document chunks + blob are removed, preventing deleted files from appearing in search results.
• Introduce WorkspaceDataSourceOptions to make upload validation configurable (allowed extensions, max file size, and content type mapping) instead of hardcoded values.

Technical Changes

• WorkspaceDataSourceAppService.DeleteAsync now delegates deletion logic to WorkspaceDataSourceManager.DeleteAsync.
• WorkspaceDataSourceManager.DeleteAsync now:
  • Deletes vector embeddings for processed data sources.
  • Gracefully skips vector cleanup when vector store provider is not configured/found.
  • Deletes document chunks, blob data, and the data source entity.
• Upload validation/UI now use IOptions<WorkspaceDataSourceOptions> across:
  • Application service
  • Blazor workspace data source page
  • MVC upload modal
• Localizations updated to parameterized values for:
  • AllowedFileTypes
  • MaxFileSize
• Added/updated unit tests:
  • WorkspaceDataSourceManager_Tests
  • WorkspaceDataSourceOptions_Tests

How to Test

1. Run automated tests:
   • dotnet test test/Volo.AIManagement.Domain.Tests
   • dotnet test test/Volo.AIManagement.Application.Tests
   • dotnet test test/Volo.AIManagement.EntityFrameworkCore.Tests
2. Verify data source deletion cleanup:
   • Upload and index a data source in a workspace with vector store configured.
   • Confirm document search returns results from that file.
   • Delete the data source from UI.
   • Confirm document search no longer returns content from deleted file.
3. Verify configurable upload options:
   • Configure WorkspaceDataSourceOptions with custom values (e.g., lower MaxFileSize and different extensions).
   • Confirm validation messages and UI accept behavior follow configured values.
