Pull Request Overview

This PR introduces a new “Discord Base” registry component by removing example items and registering the shared base components, utilities, and styles needed for Discord‐style UI elements.

• Replace earlier example components (hello-world, example-form, complex-component) with a single discord-base entry in registry.json and its metadata in public/r/discord-base.json.
• Add the Discord base component files (discord-base.tsx, discord-icons.tsx, lib/date-fns.ts) under registry/discord-base.
• Update project scripts and styling: rename the build script, bump shadcn version, and consolidate the global CSS base layer.

• [nitpick] The npm script name "reg:build" is not immediately clear; consider renaming it to something more descriptive like "registry:build" to align with its purpose and existing conventions.

    "reg:build": "shadcn build"

• The new formatDate utility has branching logic for today, yesterday, and older dates—consider adding unit tests that cover each branch to ensure the formatting behaves as expected.
