Safe Docker

Create a security tool, safe-docker, written in Rust, designed to allow coding agents (like Claude Code) to safely use Docker commands. This tool should act as a hook before command execution to prevent risks to the host system. Specifically, it must enforce rules to block mounting paths outside of the user's home directory ($HOME), prevent the use of dangerous flags like `--privileged` or `--network=host`, and detect indirect execution methods like `eval` or `bash -c`. It should also validate paths used in `docker cp` and `docker build` commands, and check for dangerous settings within `docker-compose.yml` files, providing clear feedback to the agent when a command is blocked.
