3mftool — unified entry point for the 3mf-stl-editor scripts.

Usage:
    3mftool info <file>
    3mftool render <in> <out.html|out.png>
    3mftool transform <in> <out> [--scale ...] [--translate ...] [--rotate-x/y/z ...]
    3mftool convert <in> <out>
    3mftool merge <file>... -o <out>
    3mftool split <in> [-o <out>] [--object-index N] [--list]
    3mftool metadata <in> [<out>] [--set K=V ...] [--remove K ...] [--list]

All subcommands forward any extra args (including --json) to the underlying
script. Behaviour and exit codes are identical to calling the scripts directly.
