…in unit-test builder Refactors the unit-test builder to introduce a generic `TestRunner` API. This change decouples the main builder logic from the specifics of individual test runners like Karma and Vitest. The new API consists of two main parts: - `TestRunner`: A declarative definition of a test runner, including its name and hooks for creating an executor and getting build options. - `TestExecutor`: A stateful object that manages a test execution session. The Karma and Vitest runners have been refactored to implement this new API. The Karma runner is now marked as `isStandalone: true` to indicate that it manages its own build process. The Vitest runner now uses the `getBuildOptions` hook to provide its build configuration to the main builder. This refactoring makes the unit-test builder more extensible, allowing for new test runners to be added more easily in the future. It also improves the separation of concerns within the builder, making the code easier to understand and maintain.
