thanhnvandClaude Opus 4.8 36a4812ef3 refactor(structure): promote app to repo root + remove redundant workspace cruft
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 Track C-MVP — Supply-chain gate for generated dependencies (C2, V18).
#
# An agent that writes code can also add a dependency. This gate diffs a
# dependency manifest against a baseline and decides:
# BLOCK malicious/denylisted package, typosquat of a known package,
# or a dangerous lifecycle script (postinstall/preinstall/install) -> exit 2
# REQUIRE_APPROVAL a genuinely new dependency was added -> exit 3
# (ALLOW+audit when CASAN_ACTION_APPROVER is set)
# ALLOW no new dependencies -> exit 0
#
# Supports: package.json, requirements.txt, pom.xml, build.gradle(.kts).
# When npm audit / pip-audit / osv-scanner are installed they are recorded as
# available; otherwise the local denylist (malicious-packages.txt) is authoritative.
# The diff/scan logic lives in supply-chain-scan.py (deterministic, no network).
#
# Usage: supply-chain-gate.sh <manifest> [baseline-manifest] [report.json]
# If baseline is omitted, the manifest's committed git version is used.
