…etherEdu#413) Implement chaos experiments for key platform dependencies (Redis, MongoDB, Stellar RPC) with automated assertions that verify graceful degradation and recovery. Experiments include: - redis-failure: complete Redis unavailability with circuit breaker verification - redis-latency: 500ms latency injection with response time thresholds - mongo-failure: MongoDB container termination with crash detection - rpc-failure: Stellar RPC endpoint blocking with connectivity checks - pod-termination: backend container SIGKILL with RTO measurement The orchestration script produces structured JSON reports, supports dry-run mode, and is integrated into CI via a weekly scheduled GitHub Actions workflow with workflow_dispatch support for on-demand runs. Documentation includes a comprehensive resilience runbook with interpreting results, common failure causes, and a feedback loop for feeding findings into platform improvements. Closes AetherEdu#413

Summary
Implements the chaos engineering and resilience test suite defined in #413.
