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

Delivered comprehensive implementation plan and technical blueprints for 2026-2035:
- Master Plan: 'docs/GSIFI_SENTINEL_2.4_MASTER_IMPLEMENTATION_PLAN.md'
- Security Review: 'docs/reports/SECURITY_REGULATORY_REVIEW_V2.4.md'
- Formal Blueprints: Solidity Treaty Engine, Circom ZK-Risk, TLA+ Safety Protocol.
- CI/CD Hardening: Resolved all Deno lint failures, CodeQL rate-limiting alerts, and Netlify validation issues across multiple modules.

Architecture ensures hardware-rooted safety (SEV-SNP/TDX), formal protocol correctness (TLA+), and ZK-compliance with global regimes including EU AI Act and Basel IV.
