feat(governance): implement Sentinel AI Governance Stack v2.4 (2026-2035) for G-SIFIs

- Materialize formal governance blueprints in `governance_blueprint/`:
  - `OmegaActualTreatyEngine.sol`: Decentralized containment & heartbeats.
  - `SystemicRiskAggregator.circom`: ZK-SNARK systemic risk proofs.
  - `SentinelContainmentProtocol.tla`: Formal safety & liveness invariants.
  - `confidential_enclave_deployment.tf`: Hardened multi-region enclave provisioning.
- Add comprehensive implementation and safety documentation:
  - `docs/GSIFI_SENTINEL_2.4_MASTER_IMPLEMENTATION_PLAN.md`: 2026-2035 roadmap.
  - `docs/reports/SECURITY_REGULATORY_REVIEW_V2.4.md`: Compliance mapping.
- Fix CI/CD and linting violations across the repository:
  - Resolve Deno linting errors in `next-app`, `frontend`, and `backend`.
  - Add explicit `node:process` and `node:buffer` imports for environment compatibility.
  - Implement `express-rate-limit` in `server.js` to address CodeQL security alerts.
  - Harden Terraform configuration for Terrascan compliance.
  - Standardize Netlify `_headers` and `_redirects` formatting for validation gates.
- Verified architecture with `make daily-gsifi-governance-checks`.
