 * Most Tia services (`Recorder`, `CoverageCollector`, `WatchPatterns`,
 * `ResultCollector`, `BaselineSync`) are auto-buildable — Pest's container
 * resolves them lazily via constructor reflection. The only service that
 * requires an explicit binding is the `State` contract, because the
 * filesystem implementation needs a root-directory string that reflection
 * can't infer.
