feat: add ai category with vercel-ai-sdk and tanstack-ai modules

- Register a new `ai` category in `CATEGORIES` (cardinality `one`, home `packages/ai/`) so both modules land under the same single-choice slot
- Add `ai-vercel-ai-sdk`: installs `ai` + `@ai-sdk/openai`, emits a `model.ts` configured for `gpt-4o-mini`, a shared package entry-point, and a streaming `/api/chat` route for Next.js (`StreamingTextResponse`) and TanStack Start (`EventStream`); peers on `framework`
- Add `ai-tanstack-ai`: installs `@tanstack/ai` + `@tanstack/ai-openai`, emits an `adapter.ts` wrapping `openaiText("gpt-4o-mini")`, a shared entry-point, and a streaming `/api/chat` route for both frameworks via `toServerSentEventsResponse`; peers on `framework`
- Both modules declare `OPENAI_API_KEY` in `env` and ship provider-swap instructions in `readme.md`
- Update `registry.mdx` AI table: mark both modules 🟢 Available with short capability notes
