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 Risk Aggregator, TLA+ Safety Protocol.
- CI/CD & Security Hardening: Resolved Deno lint failures, DevSecOps terrascan violations, and Netlify deployment formatting issues across multiple modules.

Architecture integrates AMD SEV-SNP/Intel TDX enclaves, Groth16 zk-SNARKs, and PQC-ready WORM audit logs.
