This commit introduces a multi-level debug logging system within the Vitest test runner's executor. This logging is intended to aid in troubleshooting internal issues and provide deeper insights into the test execution process. Logging is controlled by the `NG_TEST_LOG` environment variable, which accepts numeric levels (0 for off, 1 for debug, 2 for verbose). Crucial lifecycle events and state changes in the `VitestExecutor` are now logged, such as constructor instantiation, build result processing (full and incremental), test re-run specifications, Vitest initialization details (including browser configuration, external configuration path, and included files), and executor disposal. These logs are guarded by the `logLevel` to prevent any performance penalties during normal execution. Furthermore, specific areas like incremental run file mappings and external dependency metadata are logged at a verbose level.
