 - Image operations: pull/list/delete with curated quick picks and custom image support.
-- Script-to-image workflow: generate Dockerfile from bash script, then optionally build.
-- MySQL quick start flow with version/password/port prompts.
 - Docker Engine API access through `/var/run/docker.sock` for structured list and lifecycle operations.
 - Direct `fork`/`exec` process execution for CLI-backed streaming and interactive commands.
 - Persistent container listings that retain exited containers.
