/tdd -- Red-Green-Refactor for .NET

What

Guides a strict test-driven development cycle for .NET features. Instead of writing implementation first and bolting on tests after, this command flips the order: write a failing test that defines the desired behavior, implement the minimum code to make it pass, then refactor with confidence.

Every cycle uses the .NET testing stack:

• xUnit v3 -- Test framework with [Fact] and [Theory]
• WebApplicationFactory -- Integration tests against the real HTTP pipeline
• Testcontainers -- Real databases (PostgreSQL, SQL Server) in tests
• Verify -- Snapshot testing for complex response structures
• FakeTimeProvider -- Deterministic time in tests
