feat(plan-01): Phase 3 — split domain OKR data into apps/okr/domain

Separate per-project domain data from the reusable harness so packages/casan-harness
holds no domain artifacts. Domain data physically relocated to apps/okr/domain, with
compat symlinks at the old paths (Python + app + evidence-log refs keep resolving).

Moved -> apps/okr/domain (+ compat symlink at old path):
  golden-runs/           (was .specify/level5/golden-runs)
  corpus/{redteam-corpus.jsonl,redteam-vectors.jsonl,benign-corpus/}
                         (was packages/casan-harness/security/*)
  traceability-map.json  (was .specify/traceability-map.json)
  input/                 (was docs/input — OKR requirement/architecture)

casan-paths.sh: add CASAN_DOMAIN_ROOT (apps/okr/domain; env-overridable so Plan-06 can
point a second app at its own domain; falls back to .specify pre-split).

Harness bash refs repointed to $CASAN_DOMAIN_ROOT: run-casan4 (golden), phase3-redteam
(corpus), phase-h4-multilingual/split-inject (benign-corpus), phase10-traceability (map),
benign-fp-report (corpus+vectors). Python + app refs still resolve via the compat
symlinks (repointed in Phase 4 when the symlinks are removed).

Full gate: PASS=64 FAIL=0 SKIP=3 (CASAN_CI_STEP_TIMEOUT_SEC=1200). A first gate run
crawled under host load avg ~30 (Ollama + system); re-run at lower load passed clean.
