Standard production layout: the OKR app (was nested under AINative_OKR_CASAN5/) is now
the repository root. No more wrapper directory.

- Promote AINative_OKR_CASAN5/* -> repo root (backend/ frontend/ packages/ apps/
  .specify/ docs/ infra/ nginx/ scripts/ + configs). Merge tool dirs: .gitea (kept the
  active deploy ci.yml, added harness-ci.yml + runbooks), .claude (agents/commands +
  launch.json), .github moved up.
- Remove redundant: 00_SUBMISSION_PACKAGE, scattered root notes (FPT_CASAN_Full.md,
  tu-tuong-casan.md, casan-tu-sinh..., casan_harness_assessment.md, source-review...,
  README_CASAN5_REFINED.md), casan-next-plans/ and optimize-docs/ (competition/planning
  artifacts — roadmap + design history preserved in git log / commit messages).
- Update all references to the old layout:
  - .gitea/workflows/{ci,harness-ci}.yml, .github/workflows/{ci,deploy}.yml:
    working-directory .; drop AINative_OKR_CASAN5/ prefix; .specify/{tests,scripts}
    -> packages/casan-harness/... (.specify/logs state kept)
  - .claude/launch.json, .gitea/*-runbook.md: path prefixes
  - CLAUDE.md, README.md: docs/input -> apps/okr/domain/input
  - policy-bundle.yaml: 8 policy paths -> packages/casan-harness/...; manifest re-signed
- secrets-scan.sh: fixture excludes -> new package/domain paths.

Full gate from the new root: PASS=64 FAIL=0 SKIP=3.

# CASAN Plan-16 SEC-25 (SC-07, offline) — build-artifact attestation (tested==deployed).
#
# A green CI gate proves the TESTED artifact is sound, but nothing binds it to what
# is DEPLOYED — a different artifact could ship. This produces a signed attestation
# over an artifact's content hash; verification recomputes the hash and checks the
# signature, so a swapped/modified artifact (deployed != tested) or a forged
# attestation is REFUSED (fail-closed). Offline form of SLSA-style provenance;
# real signed-commit enrollment + full provenance chain need CI/key infra.
#
# Usage:
# artifact-attest.sh attest <artifact> <priv-key> # -> <artifact>.att (+ .att.sig)
# artifact-attest.sh verify <artifact> <attestation> <pub> # tested==deployed check
# Exit: 0 ok · 2 mismatch/forged/tampered · 3 missing/unsigned/openssl · 64 usage.
