Description

This PR introduces a BullMQ-backed risk analysis worker to support asynchronous transaction risk evaluation for autonomous agents.

The implementation extends the existing risk module to evaluate transaction behavior using historical baseline metrics, persist risk assessments through the existing risk service, and emit alerts when transactions exceed high-risk thresholds.

Changes Made

• Risk Analysis Worker: Added risk-analysis.worker.ts to process transaction evaluation jobs asynchronously using BullMQ.
• Historical Baseline Analysis: Added comparisons for transaction frequency and transfer amounts against supplied historical metrics.
• Risk Scoring Integration: Integrated the worker with the existing RiskService for risk assessment and persistence.
• Risk Alerts: Added event emission for transactions classified as HIGH or CRITICAL.
• Module Integration: Registered the worker in RiskModule.
• Unit Tests: Added tests covering job processing, historical baseline calculations, invalid inputs, and risk alert boundaries.

Testing

Added unit tests in risk-analysis.worker.spec.ts.

Note: Tests have not yet been executed, and CI results are pending.

Outstanding Work

• Connect transaction events to BullMQ job enqueueing.
• Enforce mandatory human/multi-signature approval or wallet freezing for critical-risk transactions.
• Validate the complete worker integration.

I’m holding this PR because the description explicitly identifies it as a partial implementation: transaction events are not yet connected to queue enqueueing, and the mandatory human/multisignature approval or wallet-freeze behavior for critical risk is still outstanding. Please complete or narrow the PR to the issue’s satisfied acceptance criteria before merge.
