Dark Gravity Integration & Technological Sovereignty Policy

This PR updates the repository README to formalize:

1. Architectural Role in Dark Gravity Autonomous Software Factory: How this sovereign fork provides critical infrastructure capabilities.
2. Technological Sovereignty & Independent Maintenance: Rationale for maintaining this hardened fork following upstream MinIO licensing shifts and closure, ensuring zero-CVE posture and total operational independence.
3. Traceability: Direct alignment with the Dark Gravity Architecture Knowledge Base.
