New monorepo support in the CLI.

Until now, using shadcn/ui in a monorepo was a bit of a pain. You could add components using the CLI, but you had to manage where the components were installed and manually fix import paths.

With the new monorepo support in the CLI, we've made it a lot easier to use shadcn/ui in a monorepo.

The CLI now understands the monorepo structure and will install the components, dependencies and registry dependencies to the correct paths and handle imports for you.
