feat(container): add podman rewrite support

[YOMXXX]

Summary

• Add podman rewrite rules so direct podman ps/images/logs/run/exec/build/compose ... invocations route through RTK.
• Add an rtk podman CLI path that reuses the existing docker/container formatters while executing the podman binary.
• Generalize container tracking labels, output prefixes, compose execution, and passthrough routing for docker vs podman.
• Add regression coverage for podman classification, rewrite, compose rewrite, and CLI parsing.

Fixes #2548
