feat: add wm-toggle-pause command

[michidk]

This is my try to implement the pause command I proposed in #825.

Basically, this adds the command wm-toggle-pause which pauses glazewm from managing windows.

Feedback is very welcome. This is my first contribution to glazewm and I'm not too familiar with the codebase yet.

Ay this is super cool 👌 Thanks for putting together the IPC side of it as well.

A downside with returning early in all these platform events is that state will be out of sync on resume. Like say a monitor was unplugged, the WM would still think it has all its monitors.

Perhaps it'd be better to instead skip redraws if the WM is paused:

// wm.rs - https://github.com/glzr-io/glazewm/blob/940bb4cc474898aa3b1ffda2f29720e37bb7a16c/packages/wm/src/wm.rs#L128
..
    if state.is_paused {
      platform_sync(state, config)?;
    }

and then also disable keyboard/mouse listener on pause:

// main.rs - https://github.com/glzr-io/glazewm/blob/940bb4cc474898aa3b1ffda2f29720e37bb7a16c/packages/wm/src/main.rs#L162
..
        if matches!(
          wm_event,
          WmEvent::UserConfigChanged { .. }
            | WmEvent::BindingModesChanged { .. }
            | WmEvent::PauseChanged { .. }
        ) {
          event_listener.update(
            &config,
            &wm.state.binding_modes,
            is_paused
          );
        }

Hi @lars-berger,

My new implementation to block mouse events goes probably into the right direction.

But there is one problem with blocking key events: The keybinding to unpause won't be recognized as well.

However, I went forward and implemented something:
If you think this is an alright approach, I would go and implement the last missing part:
https://github.com/michidk/glazewm/blob/pause/packages/wm/src/common/platform/keyboard_hook.rs#L365
(detecting if the keybind is for unpausing and then not blocking it).

I finished & tested the implementation!
Next, I'm going to start working on the necessary changes in zebar for displaying the paused state.

[michidk]

Done.

All merged now! Thanks for getting it all nicely integrated with the NPM library + zebar as well 🙌

Found a couple minor things while testing it out more thoroughly #870. Also did a super nitpicky rename to is_paused since that seems more consistent with our other boolean properties like has_focus, is_displayed...

Thanks again for the massive help on this ❤️

I actually had used is_paused in some iterations as well, but then removed it again.

I think right now we sometimes have still paused in the NPM library but I guess that's fine.

Thank you for finishing this up and sorry for missing the resize & IPC events!
