Provide a meta-command to output interpolated deno command strings

## Issue Type

- Feature Request

This screenshot is shown in the readme:


After running the command, it shows this text in `stdout`:

> Running main script with allow-read, seed and reload options ...

This doesn't appear in the current version of denox. I don't know why for certain, but I agree that it shouldn't be in `stdout` for multiple reasons.

However, this is the core functionality of denox: to interpolate commands for proxying to `deno`.

It would be extremely useful for denox to provide the interpolated command strings using a prefix like `command`, for example:

`deno-workspace.yaml`
```yaml
scripts:
main:
file: main.ts
deno_options:
allow-net: example.com
unstable: true
```

```shell
> denox command run main script args
deno run --allow-net=example.com --unstable main.ts script args
```

This would be useful for understanding how denox is parsing the workspace file and could potentially help to debug denox in the future.

## Info

- DenoX version: `0.4.0`

Read the CLI command handling and workspace interpolation logic, using the deno-workspace.yaml example in the issue as the starting case. Add a command prefix that prints the interpolated Deno command, then verify that the example produces the shown deno run invocation with its arguments.
