Drop dead frontend code + consolidate eval scripts under tests/quality

frontend/ — two dead files removed
- frontend/src/components/backend-health-card.tsx
  Health-check card from early dev. Confirmed orphaned by a strict
  importer scan (zero hits in frontend/src/ for either the file
  path or the BackendHealthCard symbol).
- frontend/src/state/workspace-store.ts
  Zustand store stub. Comment in the file references the deleted
  docs/NEXT-STEPS-FRONTEND.md and admits "only the `ui` slice is
  implemented." The redesign chose hooks + lifted callbacks over
  Zustand, so this file is the abandoned approach.

scripts/ → tests/quality/
The repo had two utility scripts at the root in their own folder:
eval_resume_parser.py and perf_assistant_stream.py. They're
evaluation/perf runners — same role as the 13 *_quality_runner.py
files already in tests/quality/. Co-locating them removes the
awkward two-file scripts/ folder.

- scripts/eval_resume_parser.py   → tests/quality/eval_resume_parser.py
  REPO_ROOT bumped from `parent.parent` to `parent.parent.parent`
  (file moved one level deeper in the tree, so the parent climb
  needs to compensate).
- scripts/perf_assistant_stream.py → tests/quality/perf_assistant_stream.py
  Updated 3 docstring usage-example commands to point at the new
  path (`tests/quality/perf_assistant_stream.py`).

The empty scripts/ folder was removed.
