Remove parked security-review CI drafts

CI was swapped for the global git hooks + nightly VM sweep (solo dev), so
the parked ci/*.yml and CI-BACKSTOP-NOTES.md were dead weight — a defective
workflow in-tree is a foot-gun. Recover from history if the team grows.

-# Sea Haven security-review CI backstop (Phase 3).
-# Drop into a target repo as .github/workflows/security-review.yml, OR (preferred, per
-# engineering-handbook/cicd.md) promote into Sea-Haven-Industries/.github as a reusable workflow.

-# This is the UNBYPASSABLE deterministic backstop: local hooks can be skipped with --no-verify,
-# this cannot. It runs the SAME review.sh as local. The agentic detector/verifier pass (Path B)
-# is gated behind SECURITY_REVIEW_AGENTIC=1 and requires the headless orchestrator runner +
-# ANTHROPIC creds (see DEPLOY-R720.md) — until that exists, CI runs the scanners-only gate.
