feat(meta-validate): add batch mode — pipe-separated paths

Accept multiple object paths via pipe separator (|) in -ObjectPath.
Each object is validated separately with individual results, followed
by a summary line: "Batch: N objects, X passed, Y failed".
Single-path mode unchanged. Version bumped to v1.1.
