modules/niri: implement hot-reloading

[zimward]

This currently requires niri-git and there seems to be a bug in the switch-to-generation logic to actually trigger an automatic reload, but atleast manual works.

Is this something we should be doing too? We can add it via like, config.buildCommand.fixNiriReload = { after = [ "symlinkScript" ]; data = basically_that; }; or config.drv.buildPhase = basically_that;

so far for a reason i have yet to figure out the systemd unit doesn't actually gets reloaded by switch-to-configuration. i need to look into it once i have a bit more free time.

TYSM I don't use niri but I try to keep an eye out for things that may help.

Sadly, restarting user units is just broken: NixOS/nixpkgs#246611
