Module container 

Container name resolution for Docker/Podman.

Resolves process PIDs to container names using:

• Linux: /proc/{pid}/cgroup → container ID → docker ps lookup
• macOS: docker ps with PID matching via docker inspect

All lookups are batched per refresh cycle to minimize CLI overhead. Missing Docker/Podman is handled gracefully (empty results, no errors).

Functions

has_containers

Check if any entries have container names (used for adaptive column).

resolve_container_names

Resolve container names for a batch of PIDs.
