test: one owner per case id, a structural devex 0B setup rule, and correct design/gbrain actors

- plan-design-review-plan-mode was registered by two files; the PTY smoke is
  now plan-design-review-plan-mode-smoke, and a registry test requires one
  owner per case in case-sharded files.
- plan-devex-finding-floor: the template's 0B narrative-confirmation question
  is classified as setup structurally instead of timing out a Haiku assessor.
- setup-gbrain-remote: the actor accepted 'skip' on the MCP-registration
  question the test asserts; it now accepts that question and declines others.
- design-review-plugin-handoff: the fake engine cited a file absent from the
  fixture repo and index.html linked a missing styles.css.
Captured-question regressions with negative controls; each case passed a
focused paid run.
