Migrates the repo off `clsx` + `tailwind-merge` to
[shadcn-ui/cn](https://github.com/shadcn-ui/cn). Every app and package
already gets `cn` from `packages/ui`, so the swap happens in that one
helper and flows through to Studio, docs, www, and the rest.
**Changed:**
- `packages/ui` `cn` helper now uses `createCn` from `cn/config`,
keeping the custom `card`/`content` spacing scale so `p-card` still
overrides `p-4`. It has an explicit signature and re-exports
`ClassValue`.
- The four www Launch Week files that imported the `ClassValue` type
from `clsx` now import it from `ui`.
- `blocks/vue` local `lib/utils.ts` re-exports `cn` from the package.
- Comments/README that referenced tailwind-merge.
**Removed:**
- Direct `clsx` and `tailwind-merge` deps from `ui`, `ui-patterns`,
`www`, and `blocks/vue`. `ui-patterns` and `www` declared them without
importing.
**Added:**
- `packages/ui/src/lib/utils/cn.test.ts` covering clsx-style joining,
conflict resolution, the custom spacing scale, and variant handling.
Not migrated: the standalone apps under `examples/`. They're outside the
workspace and mostly on Tailwind v3, which `cn` doesn't support.
Lockfile note: after merging master, the lockfile diff is only the
intended swap (`clsx` and `tailwind-merge` out, `cn@0.2.5` in).
`tailwind-merge` stays in the lockfile as a transitive dep of a
third-party package.
Release-age note: this sat in draft with a temporary
`minimumReleaseAgeExclude` entry for `cn` while `cn` was inside the
workspace's 3-day `minimumReleaseAge` window. That window has closed, so
the exclusion is gone and nothing bypasses the release-age gate.
## To test
- `pnpm install --frozen-lockfile` succeeds with no
`minimumReleaseAgeExclude` entry for `cn`.
- `pnpm --filter ui test` – new `cn.test.ts` passes, including
`cn('p-4', 'p-card')` → `p-card`.
- Typecheck passes for studio, ui, ui-patterns, vue-blocks. www
typecheck panics under tsgo on master already (pre-existing, unrelated);
it passes with the JS `tsc` binary.
- Spot-check Studio locally: class overrides still win in the usual
places (e.g. `CodeEditor` height, `Button` variants with a custom
`className`).
