feat: implement Sentinel AI Governance Stack v2.4 & G-SIFI Master Plan

Delivered comprehensive architectural blueprints and implementation strategy:
- Master Plan & Security Review docs for 2026-2035 G-SIFI roadmap.
- Formal Blueprints: Solidity Treaty Engine, Circom ZK-Risk, TLA+ Safety Protocol.
- Production-grade Terraform for confidential enclaves (SEV-SNP/TDX).
- CI/CD & Security Hardening: Resolved all Deno linting, CodeQL rate-limit, and Netlify validation issues.

Architecture integrates hardware-rooted safety (PCR_MATCH=TRUE), formal correctness (TLA+), and ZK-compliance with global regimes (EU AI Act, Basel IV).
