fix schema import to use server-safe subpath (#146)

- `@json-render/react` barrel-imports React contexts that call `createContext`, which crashes in Next.js App Router API routes (RSC runtime strips `createContext`)
- Updated all docs, READMEs, examples, and skills to import `schema` from `@json-render/react/schema` instead of `@json-render/react`
- For combined imports, split into separate `schema` (subpath) and client API (main entry) lines

Fixes #123
