docs: update ROADMAP and design doc for Phase A completion, export defineInterface

- Export defineInterface from root index.ts (reviewer suggestion)
- Mark ROADMAP Phase A items as complete
- Update ROADMAP metrics (199 test files, 5468 tests, 177 schema files)
- Update Phase 1 deliverables with Interface/content elements
- Add defineInterface() to DX helper list
- Update design doc status from "Proposal" to "Phase A Implemented"
- Mark design doc Phase A checklist items complete
- Add decisions #6-8 to design doc decision log (PageSchema merge, SortItemSchema, branding extend)
