Proposing an asqav custom guardrail integration for LiteLLM that adds cryptographic audit trails to every LLM call passing through the proxy.

**What it would do:** - Sign every LLM request/response with ML-DSA-65 (quantum-safe) - Create tamper-proof audit logs with independent verification URLs - Enforce policy gates (rate limits, content policies, required approvals) - EU AI Act / SOC2 / HIPAA compliance evidence out of the box

**Implementation:** Would extend LiteLLM's `CustomGuardrail` base class to hook into pre-call and post-call events.

asqav is MIT licensed and already supports 100+ LLM providers through its SDK.
