feat(coverage): write the Clover report to an IDE-managed path

Drop the getCoverageFilePath override that hardcoded <project>/runtime/clover.xml
and pass the report path to the CLI via --coverage-clover=<path> instead. The
path now comes from the platform default (<system>/coverage/<project>@<config>.xml),
exactly like the PhpUnit/Codeception engines, so coverage no longer needs to land
in the project runtime dir. Testo's --coverage-clover flag (Symfony Console,
VALUE_REQUIRED) is confirmed in the framework source.

 /**
- * The Clover report lives inside the project (runtime/clover.xml), not under [com.intellij.openapi.application.PathManager.getSystemPath].
- * The platform's default [CoverageSuite.deleteCachedCoverageData] stays silent only for files under the system dir;
- * for a project file it pops a "Delete file '…' on disk?" confirmation on every rerun. The report is regenerated each
- * run, so we don't delete it — which also removes the prompt.
+ * The report path is IDE-managed (under [com.intellij.openapi.application.PathManager.getSystemPath]), so the platform's
+ * default delete-on-disk confirmation never fires. We still skip deletion: the report is regenerated each run at the
+ * same path, so there is nothing to clean up.
