docs(plans): sync roadmap status + paths to post-restructure state

- Plan-01 marked ✅ DONE (INDEX table + P3 tier + BACKLOG row + plan header).
- Plan-06 / Plan-12 dependency on 01 satisfied → 🔓 unblocked (headers + BACKLOG rows).
- Repoint command/path refs in all plans (except Plan-01's migration narrative):
  .specify/{scripts,tests,security,config,templates,governance} -> packages/casan-harness/...;
  golden-runs/traceability-map/docs-input -> apps/okr/domain/...; `cd AINative_OKR_CASAN5`
  -> `cd $(git rev-parse --show-toplevel)`; fix relative links + Plan-13 control-plane location.
