allow inline theme in registry

[thibaultleouay]

When I'm defining a registry with a theme like this :

{
  "$schema": "https://ui.shadcn.com/schema/registry.json",
  "name": "runreal",
  "homepage": "https://runreal.dev",
  "items": [
    {

      "registryDependencies": [
        "http://localhost/r/runreal-theme.json"
      ],
      "files": [
        {
          "path": "registry/components/corner.tsx",
          "type": "registry:component"
        }
      ]
    },
   
    {

          "in-out-quart": "cubic-bezier(0.77, 0, 0.175, 1)",
          "in-out-quint": "cubic-bezier(0.86, 0, 0.07, 1)",

          "100%": {
            "transform": "translateX(100%)",
            "background-position": "-100% 0"
          }
        }
      }
    }
  ]
}

When building a registry, the registry:theme was not generated, but I need it to apply style.
After this PR, the build command will also create a new file for the registry-theme.
(If I added my registry item to my files array, the content would have been added to content, and cssVar wouldn't be applied.)

I'm +1 on this but would like to explore if there are other registry items that could use a non-optional files. I'm working on registry:add type which can add to existing files for eg.

Let me think.

(@thibaultleouay are you blocked by this? any workaround you can use for now?)

[thibaultleouay]

The workaround is to add the same css Var to all the items

A lot of copy paste code

But theme item with the current registry is not working

[thibaultleouay]

An other workaround is the following
I have theme in my registry components and before deploying it i'm copying it into my public folder

because it won't get build/package by the cli

pnpm registry:build  && cp ./registry/components/theme.json ./public/r/theme.json 

and in my components i have a registry dependencies pointing to this files

[shadcn]

what if the theme is its own registry item and you add it a registryDependency for the other items?
