Implement support for tracing multiple containers within a single Kubernetes pod. This completes Milestone 4. Changes: - Add -cgroups flag for comma-separated cgroup paths - Maintain backwards compatibility with -cgroup flag - Add CgroupPaths []string field to Config - Create helper utilities for container discovery - Add comprehensive tests (all passing) - Document multi-container usage patterns - Include complete working example manifest The implementation supports up to 64 containers per pod (eBPF map limit) and allows selective tracing of specific containers while excluding others (e.g., snoop's own container).
