feat(schema): redirect non-schema paths to native-sdk.dev (#388)

* feat(schema): redirect non-schema paths to native-sdk.dev

- schema.native-sdk.dev now serves only /app/v1.json and its /app.json alias
- Every other path catches and redirects (302) to https://native-sdk.dev
- Update pinned docs check and schema README to match the new routing

* fix(schema): redirect non-schema paths

 - `/app/v1.json` is the stable-major schema URL scaffolded into `app.json`.
 - `/app.json` is the short-lived current-version alias.
 
+Only those schema URLs are served from this deployment. Every other path
+redirects (302) to `https://native-sdk.dev`, so the domain stays a single-
+purpose home for the manifest rather than hosting arbitrary content.

 Create the Vercel project as `native-schema`, set its root directory to
 `apps/schema`, leave the framework preset as Other with no build command, and
 attach `schema.native-sdk.dev`. `vercel.json` sets the output directory to

apps/schema/vercel.json
