router: cli: avoid unnecessary clones/allocation

Browse Source 
The `new_args` Vec is directly passed to the other Vec's `.extend()`,
which takes an `IntoIterator` consuming it, so just pass the
intermediate `Iterator`.

The `rest` Vec owns its strings and we don't need it afterwards, so
similarly, we can consume it via `.extend()` instead of a manual
push(s.clone()) loop.

The .truncate(0) can just be .clear() - they are equivalent according
to their documentation.
