Add Determs — verifiable LLM decision audit records (VDR spec + SDK)

[nullcb]

Determs is an open specification (Verifiable Decision Record) and reference implementation for capturing each LLM call as a verifiable, independently-checkable audit record.

Added to the Observability section alongside QWED and other audit-adjacent tools.

Distinction from monitoring tools: not a dashboard or trace aggregator — a cryptographic record layer. Each call produces a self-contained record with stable digests that any party can verify with public infrastructure, no account needed.

• Python SDK wraps Anthropic + OpenAI clients (drop-in, no code change required)
• Rust CLI: verify, replay, hash, capture
• Optional public anchor (OpenTimestamps) for tamper-evident existence-in-time
• Evidence packs for EU AI Act Art. 12/19 compliance
