## What kind of change does this PR introduce?
Chore.
## What is the current behaviour?
Classic Dark remains available across the shared theme library and
several apps. Studio now supports System, Dark, and Light as its theme
modes, but still carries compatibility paths for Classic Dark.
## What is the new behaviour?
- Removes Classic Dark from shared theme options, application commands,
stylesheets, previews, examples, and replay handling.
- Deletes the Classic Dark and faux Classic Dark stylesheets.
- Removes the now-unused Classic Dark branches from Studio theme colour
controls.
- Migrates `classic-dark` to `dark` so first rendered frame renders Dark
(not Light)

## To test
1. In Studio, open Account Preferences → Appearance. Confirm the
available themes are System, Dark, and Light, and that theme colour
controls still work in each resolved mode.
2. Set the `theme` local storage value to `classic-dark`, then reload
Studio. Confirm it renders as Dark immediately and the stored value
becomes `dark`.
3. Open the theme switcher in Design System, Learn, and UI Library.
Confirm Classic Dark is no longer available and Light, Dark, and System
still apply correctly.

Our UI Library registry is expanding to include blocks that go beyond UI
and in some cases focus purely on back-end. This PR is a precursor to
adding more back-end related blocks. This PR includes the `ui-library ->
library` rename plus redirects and small UI copy updates. Since this is
a rename we'll need to update Vercel configuration.
## Vercel rollout
Keep the Library project Root Directory as `apps/ui-library`
1. In the **Library** Vercel project, set:
`NEXT_PUBLIC_BASE_PATH=/library`
Apply it to Preview and Production, then redeploy the Library project.
2. In the **www** Vercel project, add:
`NEXT_PUBLIC_LIBRARY_URL=<current value of NEXT_PUBLIC_UI_LIBRARY_URL>`
Apply it to Preview and Production. Keep `NEXT_PUBLIC_UI_LIBRARY_URL`
during the migration, then redeploy the www project.
3. Deploy in this order:
1. Library project
2. www project
4. Validate:
- `/library`
- `/library/docs/nextjs/password-based-auth`
- `/ui` redirects to `/library`
- `/ui/docs/nextjs/password-based-auth` redirects to
`/library/docs/nextjs/password-based-auth`
- `/ui/docs/ai-editors-rules/*` still uses its existing Docs redirects
No Vercel dashboard redirect rules are needed. Environment-variable
changes require a new deployment.

## Summary by CodeRabbit
* **New Features**

navigation, pages, documentation, and resource links.
* The Library is now available at `/library`, with updated descriptions
covering components, blocks, and developer tools.
* **Bug Fixes**
* Added permanent redirects from legacy `/ui` URLs to corresponding
`/library` paths.
* Updated links throughout the site and documentation to prevent broken
navigation and references.

## Problem
Our `<Button>` component breaks the default `button` contract by
redefining the `type` prop to set its variant (`primary`, `default`,
etc) instead of the button type (`submit`, `button`, etc).
This is confusing and forces to write more code when using it with
shadcn components that expect/inject the standard button props.
## Solution
- rename the `type` prop to `variant`
- rename the `htmlType` prop to `type`
- propagate the changes where necessary
- format code
## How to test
As this is just prop renaming, if it builds it's ok

## Problem
The `_Shadcn_` suffix isn't needed anymore on `Command` components
## Solution
- Remove the `_Shadcn_` suffix
- Simplify UI package exports
- Apply prettier

## Summary by CodeRabbit
* **Refactor**
* Simplified command component imports and exports across the UI library
by removing internal naming aliases and adopting direct component
references. Updated the public UI package barrel export to use wildcard
re-exports for cleaner API surface.

This PR migrates the whole monorepo to use Tailwind v4:
- Removed `@tailwindcss/container-queries` plugin since it's included by
default in v4,
- Bump all instances of Tailwind to v4. Made minimal changes to the
shared config to remove non-supported features (`alpha` mentions),
- Migrate all apps to be compatible with v4 configs,
- Fix the `typography.css` import in 3 apps,
- Add missing rules which were included by default in v3,
- Run `pnpm dlx @tailwindcss/upgrade` on all apps, which renames a lot
of classes
- Rename all misnamed classes according to
https://tailwindcss.com/docs/upgrade-guide#renamed-utilities in all
apps.
