feat: ZeroClaw compliance agent — document analysis + role assignment + email

Add autonomous compliance agent that fetches web documents (cookie banners,
privacy policies), classifies them via Qwen/Ollama, assesses DSGVO compliance,
assigns to the responsible role, and sends notification emails.

Components:
- ZeroClaw SOP (6-step workflow: fetch, classify, assess, summarize, assign, notify)
- Backend: /api/compliance/agent/analyze (combined endpoint)
- Backend: /api/compliance/agent/notify (standalone email)
- Frontend: /sdk/agent page (Manager UI with URL input + results)
- Helper scripts + E2E test
