test(get): batch coverage for get.rs envelope shapes

Seven tests in new  covering get.rs
branches not driven by existing get_invariants / get_edge_cases:

  - multi-patch by PURL: emits selection_required / partial_failure
  - --id flag with no match: errors
  - UUID 404 / 500 / malformed-JSON: not_found / error / error
  - CVE / GHSA empty-result: no_match envelope

Each test mocks the minimum endpoint surface needed and asserts on
the JSON envelope's stable status field.
