fix: remove @theme inline to fix Tailwind v4 CSS conflicts

- Remove @theme inline block that was overriding Tailwind v4 defaults
- Remove custom spacing config causing utility conflicts
- Add .changeset directory for release workflow

The @theme inline directive in Tailwind v4 overrides internal theme
tokens, which was causing text-center, mx-auto, and other utilities
to not work correctly in production builds.
