Builtiin "Crush config" skill + experimental thing

We have a couple new feats on this release. Let's check them out!

Built-in "Crush config" skill

Starting on this release, Crush has the concept "built-in skills". Those are skill built in Crush, so you don't need to manually copy them to your machine or project.

For now we have a single one: "Crush config". Crush can now configure itself, so if you don't want to manually edit your crush.json config, you can just ask Crush itself to do it for you. You can ask it to add a custom providers, add a MCP, add a LSP, change a setting, etc.

Disable skill

We also added the ability to disable skills, no matter if built-in, global or project skill. Just add this to your crush.json:

{
  "$schema": "https://charm.land/crush.json",
  "options": {
    "disabled_skills": ["crush-config"]
  }
}

Experimental server-client architecture

If you run Crush with CRUSH_CLIENT_SERVER=1, it'll now run via a brand new server-client architecture.

Keep in mind, though, this is VERY experimental! There are known bugs when using Crush in this mode. We'll be polishing it with time and only make it the default once it's stable.

Happy Easter!
Charm ✨
