The PR title/description focuses on adding a Vitest unit test suite for the MCP server, but the diff includes significant additional scope (C# docs backend, CLI command, workspace/build wiring, generated docs). Either update the PR title/description to reflect the actual scope or split these changes into separate PRs to keep review and release risk manageable.

packages/igniteui-mcp/docs-backend/tests-docs-backend/UnitTest1.cs

The test class name is descriptive (DocsControllerTests), but the file name UnitTest1.cs is not. Rename the file to match its contents (e.g., DocsControllerTests.cs) to keep the test project navigable as it grows.

@copilot apply changes based on this feedback

Renamed in commit 21be234 — UnitTest1.cs → DocsControllerTests.cs.
