Done. Available command in pi:
  /edc             interactive EDC menu (review, delivery-review, status, build, update, audit, doctor)

Visible skills:
  edc-review       security/adversarial review methodology
  edc-audit        code quality / maintainability audit methodology
  edc-delivery-review
                   goal/spec delivery + architecture-fit review methodology

Mode toggle (per-project, after context has been built):
  bash pi/install.sh --context-mode advisory   # docs only (default)
  bash pi/install.sh --context-mode inject     # auto-inject context
