## Summary

- Extend `--depth` support to graphviz output format (was text/freeze
only)
- Use BFS from root nodes to limit graph depth, supporting both forward
and reverse modes
- Update CLI help text to reflect the expanded format support
- Add tests for depth=0 (roots only) and depth=1 (one level of deps)

## Details

The `--depth` flag was explicitly limited to "text and freeze render
only". This PR extends it to graphviz output by performing a BFS
traversal from root nodes and only including nodes/edges within the
specified depth.

For forward mode, root nodes are packages that aren't dependencies of
any other package. For reverse mode, root nodes are packages that aren't
parents of any other package.

When `max_depth` is infinite (the default), the original flat iteration
is used unchanged for zero overhead.

Fixes #494
