Add AI Act Companion (open-source classifier) under Risk Assessment & Classification

[JKasteele]

Thanks for maintaining this list!

Adding AI Act Companion under Open-Source Projects → Risk Assessment & Classification — a free, MIT-licensed, local-first EU AI Act risk classifier.

Why it fits the open-source section:

• Deterministic & cited — every tier verdict links to the exact Article/Annex; a rule engine, not an LLM.
• Architecture-aware AI-security lens — OWASP LLM Top 10 + MITRE ATLAS + STRIDE, severity driven by the system architecture, plus a red-team plan and matching controls.
• Also generates DPIA, Annex IV technical docs, FRIA, a conformity tracker (Art. 99 penalties) and a post-market monitoring plan; NIST AI RMF + ISO/IEC 42001 crosswalks.
• Live demo (synthetic data only); tests + CI; also ships as a Claude Code plugin and a GitHub Action.

Entry added at the end of the subsection, matching the existing format. Happy to tweak wording/placement — thanks for considering!
