Remix v0.4.0

Descripción Detallada

Minor Changes - BREAKING CHANGE: Replaced the styled button component API with a default `button()` mixin exported from `@remix-run/ui/button`. Use the mixin directly on button-like hosts instead of importing `Button` or composing the previous slot style exports: ```tsx import button from '@remix-run/ui/button' Edit order Add product Cancel ``` - Added a default `checkbox()` mixin exported from `@remix-run/ui/checkbox` for styling native checkbox inputs. Checkbox controls use the same keyboard focus shadow as `input()` controls and support an optional visual `state` for app-owned checked, unchecked, and mixed states. ```tsx import checkbox from '@remix-run/ui/checkbox' ``` - Added top-level component exports for headless primitives and styled components. Primitive-only modules import directly from their component path, while modules with styled wrappers expose lower-level behavior under `/primitives`: ```tsx import button from '@remix-run/ui/button' import as select from '@remix-run/ui/select/primitives' ``` BREAKING CHANGE: Removed the `@remix-run/ui/components/` subpath exports. Import component modules from `@remix-run/ui/*` instea
