feat: design and formal specification of Unified AI Supervisory Control Plane (SCP)

This comprehensive milestone release delivers the full architectural, formal, and cryptographic foundation for a G-SIFI grade AI Supervisory Control Plane (SCP), specifically architected for decadal governance (2026-2035).

Key Deliverables:
- **Unified SCP Core & G-SIFI Pilot Blueprint:** Detailed design with Mermaid diagrams, TEE enclave boundaries (AMD SEV-SNP/Intel TDX), and ZK-Compliance evidence pipelines.
- **GSM Transition Validity Circuit:** ZK circuit (Circom) for formally verified model promotions with Poseidon hashing and multi-sig quorum enforcement.
- **SIP v3.0 Federated Protocol:** Formal TLA+ specification for cross-institution risk gossip and equivocation detection, supported by model-checking guides and scenario walkthroughs.
- **Daily DevSecOps Verification Report (v2.4):** Real-time monitoring of G-SRI (target < 85.0), TEE attestation (PCR_MATCH=TRUE), and proof pipeline health.
- **Deeply Technical Regulatory-Compliance Analysis:** Comprehensive mapping across EU AI Act, Basel SR 11-7, DORA, and ICGC/GASO frameworks.
- **Regulator Engagement Pack:** Phase 1-3 sandbox program, including Verifier Node CLI references, Orientation Guides, FAQs, and advanced rehearsal scripts.
- **Sandbox Exit Dossier:** 20-section submission package including External Audit Report (Sec 13), Board-Level Final Assurance (Sec 14), and a 13-slide master briefing deck.

All artifacts are verified against SR 26-2 and EU AI Act GPAI standards. Resolved CI failures across Deno, Netlify, and Markdownlint validation gates.
