vivid: init

[arunoruto]

Initilize the vivid module with stylix.
With the PR nix-community/home-manager#7979 merged, it is possible to configure the module using base16 theming.

It is mainly inspired by using catppuccin themes and porting the adequate colors over from tinted theming.

Closes #560

I am not sure if the testbed is enough. Some feedback would be welcome!

The testbed is failing:

Should we resolve #1938 (comment) before merging this PR, or should we defer this to an upstream PR?

I made an issue referencing it. The module maintainer is quite active, so we should get a response pretty fast.

I also pushed a new change addressing the problem with the theme. I forced a JSON structure in the file for now, bypassing the number problem. If the response to the issue is positive regarding the 2nd point (either introducing an option or always use JSON), we can remove the "hack":

xdg.configFile."vivid/themes/${theme}.yml".source = lib.mkForce (
  pkgs.writeText "${theme}.json" (
    builtins.toJSON config.programs.vivid.themes.${theme}
  )
);

Since nix-community/home-manager#7996 got merged, I guess we can now thinker with adding the module finally to stylix.
If the way vivid is executed changes down the road in home-manager, it shouldn't influence how stylix configures it.

The tests are passing on my machine now, I guess the CI just didn't have resources now to perform it too.

LGTM after resolving #1938 (comment) by merging #2035 first.
