…lugin Refactors the Vitest unit test runner to use a dedicated plugin for merging builder-defined configurations with user-provided configurations from a `runnerConfig` file. Previously, the configuration merging logic was handled directly in the executor, which had limitations and did not always correctly apply user overrides. By moving this logic into a Vitest plugin, we leverage Vitest's intended extension mechanism, ensuring a more robust and predictable merge of configurations. This significantly improves the ability for users to customize their test setup. Adds a new test suite to verify that common custom configurations, such as custom reporters, file exclusions, option overrides, and environment settings, are correctly applied from a `vitest.config.ts` file.
