Summary

Implement new `ghq check` and `ghq cleanup` commands. `ghq check` should analyze repositories for uncommitted changes, stashes, and untracked files. `ghq cleanup` should extend this by identifying repositories not worked on recently (based on commit history and last access time) and potentially offer to remove them.
