CLI: Multiple Registries

[zbeyens]

This update adds support for multiple registries in components.json.

• See cli.mdx and changelog.mdx for details.
• I've added a minimal registry config at packages/shadcn/test/fixtures/next/public/r. This should be documented at some point.
• While not unit tested, I've added a few scripts for manual testing:
  • pnpm install --ignore-workspace in packages/shadcn/test/fixtures/next
  • dev:r1 to start the r1 app
  • init:r0 to initialize the default registry
  • init:r1 to initialize the r1 registry. You can try to run init:r0 then init:r1, or the opposite.
  • init:r2 to initialize the r2 registry
  • add:r0 to add a default component
  • add:r1 to add a component from the r1 registry
• Additionally, the init command will now fetch the registry's config.json as the default configuration to use. It falls back to the shadcn default config if not found.

Feel free to refactor with your own style.

@zbeyens Just a quick update. I'm considering this and will review. Working on an rfc before we introduce this. Thanks for the PR. It looks great.
