* DeploymentReadinessAgent - Aggregates quality signals for deployment risk assessment and go/no-go decisions
*
* Core capabilities:
* - Risk scoring algorithm (aggregates quality-gate, performance, security signals)
* - Release confidence calculation (0-100 score with thresholds: 95=GO, 70-95=REVIEW, <70=BLOCK)
* - Rollback risk prediction (deployment blast radius analysis)
* - Automated deployment checklist validation
* - Stakeholder report generation (Slack/email/dashboard)
* - Integration with quality-gate, performance-tester, security-scanner agents
*
* Memory namespaces:
* - aqe/deployment/reports/* - Deployment readiness reports
* - aqe/deployment/confidence-scores/* - Confidence calculations
* - aqe/deployment/rollback-risk/* - Rollback predictions
* - aqe/deployment/decisions/* - Go/No-Go decisions
* - aqe/deployment/checklists/* - Validation checklists
