Migrates the test suite from xUnit/NUnit to TUnit, introduces new typed data sources/base classes for FileSystem/Time/Random systems, and updates the build pipeline to use the Microsoft Testing Platform (TRX + coverage).

Key Changes:

  • Converted test attributes and data sources to TUnit equivalents ([Test], Arguments, MethodDataSource, etc.).
  • Replaced generated/fixture-based test infrastructure with new *TestData + *TestBase patterns and typed data source attributes.
  • Updated CI/build scripts and package references to run tests and produce TRX + Cobertura coverage via the new test platform.
