Add Telescope-style window picker with SUPER-TAB binding

[anagrius]

I am not so organized in where I place my windows on workspaces.
I open a window in the workspace I happen to be on, and not e.g. "The browser is always on workspace 2".

This can make it hard to find a specific window when you have many open.

This PR aims to help this problem, but adding a window picker / window switcher on SUPER-TAB.

This uses hyprctl and wofi to display a list of open window
you can quickly navigate to using the keyboard. This is great
if you don't know exactly which workspace your window is on.

Future improvements could be allowing closing windows directly from the window menu - but wofi does not support
per-row keybindings are custom actions and would probably require a custom menu system or a different tool.

There's currently 2 open PRs to replace Wofi. If the Walker PR gets merged, this isn't needed as Walker has a window-switcher built-in.

Interesting idea! I'm of the opinion that most people are better off sticking to set workspaces for set programs. That's how you really get that muscle memory to quickly jump back and forth between things down. So going to pass on this for the defaults, but you could document the setup in the Manual section of discussions. Thanks for exploring it! ✌️
