Docker Compose setup that:
- Runs metrics receiver with SQLite storage
- Spawns CPU and memory stress workloads using stress-ng
- Uses shared PID namespace (pid: service:cpu-stress) for proper isolation
- Collector gathers metrics and pushes summary on shutdown
Known issue: Container CPU summary may show overflow values on first
sample due to delta calculation - to be fixed in accumulator.
