## Type of Change
- [ ] Bug fix
- [x] New feature
- [ ] Breaking change
- [ ] Documentation update
## Motivation and Context
`container` runs each workload in an ephemeral VM, so there's no
built-in way to keep a persistent Linux environment you can log into and
work in. `container machine` adds one.
A container machine is a lightweight, persistent, and integrated Linux
environments that feel like an extension of your Mac, created from
standard OCI images with a familiar UX. The login user matches your host
account with passwordless `sudo`, your home directory is mounted inside
the VM, and each machine keeps its filesystem and runs the image's own
init system (such as`systemd` or `openrc`).
```bash
container machine create alpine:3.22 --name my-machine
container machine run -n my-machine # interactive shell
container machine set -n my-machine cpus=4 memory=8G
```
Subcommands: `create`, `run`, `list` (`ls`), `inspect`, `set`,
`set-default`, `logs`, `stop`, `delete` (`rm`); `m` aliases `machine`.
Docs added to `docs/command-reference.md` (Machine Management) and
`docs/how-to.md` ("Use container machines").
## Testing
- [x] Tested locally
- [x] Added/updated tests
- [x] Added/updated docs
