v0.3.0 — Notarize, govern, and audit AI agents

The launch release of AgentNotary (renamed from agentbox).

✨ Four new commands

• agentnotary bom — AI Bill of Materials in CycloneDX 1.6 + SPDX 2.3.
• agentnotary bench — cross-model Pareto chart of cost vs accuracy.
• agentnotary attack — adversarial fuzzer with OWASP LLM Top 10 corpus.
• agentnotary replay --rewind — time-travel debugging; fork a session at any step, edit the prompt, simulate forward.

🪪 Carrying over from v0.2 (the governance loop)

• agentnotary seal — Cargo.lock for AI agents.
• agentnotary guard run — runtime enforcement at the API boundary.
• agentnotary compliance --standard eu-ai-act — Annex IV documentation.

🔄 Backwards compatibility

• agentbox.yaml continues to parse (with a one-line stderr deprecation warning).
• apiVersion: agentbox/v0.2 still accepted.
• .agentbox/ state directories still respected.
• Migration: rename → reinstall → done.

📊 Quality

• 169 tests passing (up from 121 in v0.2).
• Ruff clean.
• CI matrix: Python 3.9 / 3.10 / 3.11 / 3.12.
