Internalize `zarf tools wait-for`

[Racer159]

Is your feature request related to a problem? Please describe

We should internalize the logic of the wait actions to that it no longer needs to shell out to Zarf.

Describe the solution you'd like

• Given I do not have Zarf on my path
• When I run a Maru task containing a wait action (either cluster or network)
• Then the wait action finishes successfully

Describe alternatives you've considered

We could not do this, or introduce another key to place this logic under but it should be relatively easy to match the current wait syntax while maintaining functionality.

Additional context

There is already a PR for some of this in Zarf: https://github.com/defenseunicorns/zarf/pull/2497/files
