feat: SWR + other-framework Query bindings, SSE/streaming, tag-based grouping

Batch D · Priority P2 · strategic

Audience-broadening bindings the React-Query-only output currently excludes:

• SWR hooks (orval, kubb) — most valuable single addition.
• Vue Query / Svelte Query / Solid Query / Angular Query (orval, kubb).
• SSE / streaming responses (text/event-stream) — increasingly relevant for AI APIs (OpenAI is in the matrix); on-brand for "agent-friendly." Pairs with the non-JSON-response client issue.
• Tag-based grouping / namespacing — large specs (OpenAI, Stripe) produce one giant flat client.ts/hooks.ts; competitors split per tag, aiding readability (a stated differentiator) and tree-shaking.

Effort: M each.
