Add visual documentation for transparency, trust, security, and ethical foundations

[Copilot]

Request to make system transparency, trust, security, ethics, and philosophical foundations visible through visual explanations.

Changes

Added 4 documentation files with Mermaid diagrams and ASCII visualizations:

• docs/ARCHITECTURE_VISUAL.md — System architecture flowcharts: trust/governance/security layers, data flow with audit trail, vertical isolation model, tunnel-only gateway security, deterministic build transparency

• docs/TRANSPARENCY_PRINCIPLES.md — Audit trail sequence diagrams, open governance policy flows, verifiable builds, data flow with jurisdiction tagging, transparency vs privacy distinction

• docs/TRUST_SECURITY_MODEL.md — Trust hierarchy (physical→identity→authorization→attestation→action), RAA trust computation logic, two-phase confirmation for high-risk actions, HSM federation threshold signing, defense-in-depth layers, zero trust model

• docs/ETHICS_PHILOSOPHY_FOUNDATIONS.md — Sovereignty principle hierarchy, safety asymptote with mathematical formulation, 5-layer ethics stack, physics-grounded principles (conservation, entropy, φ optimization, resonance), HeadyReflect protocol

• README.md — Added Visual Documentation section linking to new files

Example diagram (RAA trust computation):

DECISION LOGIC:
• ALLOW:   Risk=Low  AND Auth=Yes AND Attest=Valid
• SUSPEND: Risk=Med  AND Auth=Yes AND Attest=Valid (requires 2-phase)
• DENY:    Risk=High OR  Auth=No  OR  Attest=Invalid

All diagrams use Mermaid (GitHub-native rendering) and ASCII art for broad compatibility.

Original prompt

Pull request: #21
Ensure transparency, trust, security, the ethics, physics, philosophy, and foundations are built in the software and seen easily through ought mostly visual explanations of details
