Create comprehensive README.md

[Copilot]

The repository had a minimal 2-line README stub. Replaced with full project documentation.

Changes

• Overview: VARX Protocol description and security guarantees (authenticity, integrity, non-repudiation, replay protection)
• Architecture: ASCII diagram of three-node system (ModelNode → VARXNode → AuditorNode) with data flow
• Installation: Source install, deps-only, and dev install options
• Quick Start: Code example demonstrating keypair generation and message signing
• Project Structure: Directory tree of src/, tests/, docs/
• Development: pytest and code quality commands (black, isort, ruff, mypy)
• Security: Cryptographic primitives table (Ed25519, SHA256, HKDF, nonces)
• Contributing/License/Contact: Standard sections with org info

Quick Start Example

from core.crypto import generate_keypair, sign_message, verify_signature

private_key, public_key = generate_keypair()
request = {"type": "governance_request", "action": "data_access"}
signature = sign_message(request, private_key)
is_valid = verify_signature(request, signature, public_key)
