Core: Add a test suite

[vaxerski]

Currently we only test whether hyprland compiles, but we don't actually test... well, anything else.

This MR is a WIP that adds a test suite.

For now it runs, works, and tests spawing two kitties with smart gaps, that's about it.

TODOs:

• Test... well, more.
• Add a plugin that will be built alongside to allow for simulating keystrokes mouse strokes and other stuff
• consider thinking about visual tests?

@fufexan nix, meson, ci pls? Tester needs to be ran from /hyprtester, btw.

Good idea, but I suggest we use https://nix.dev/tutorials/nixos/integration-testing-using-virtual-machines.html. These are much simpler to use since we don't need to build our own testing framework, and there are plenty of examples to help.

I'll try to cook something up today or tomorrow if I have time.

what? Just run the tester and fail if it returns non-zero

there are a lot of magic numbers, should they be extracted?

[PaideiaDilemma]

This is cool ; )

Do we want something like swapConfig(file) in hyprtester, so that the same test can be executed with different configurations, or do we just change config options via IPC?

Also is there a reason why we don't want to allow passing the path to Hyprland binary and a path to the test suite directory right away?

swap config sounds kinda sus ngl

[nnyyxxxx]

why cant we just use the config from the examples, everything else can be done via ipc like paideia mentioned

Probably not, use the config which is in the tester directory and the rest can be IPC

No, just laziness.

easier and faster to just append a few things to a special config file
