Add Autofix helpers to @openuidev/server

[AbhinRustagi]

Summary

• Add createAutofix on @openuidev/server/openai (completions.fix / stream) and @openuidev/server/vercel (ai.fix / stream)
• Repair streamed OpenUI inside the same fence / Cloud wrapper, and expose result.content for persist
• Export Chat Completions history helpers from /openai only, plus an API reference page

const autofix = createAutofix({ apiKey, library });

await autofix.completions.fix({ generation, messages, signal });
return autofix.completions.stream({ stream: source, messages, signal }).toResponse();

return autofix.ai
  .stream({ stream: toUIMessageStream({ stream: result.stream }), signal })
  .toResponse();

Pass toUIMessageStream({ stream: result.stream }) for Vercel. Persist result.content, not joined deltas. autofix.responses is not supported yet.

Test plan

• Server build, typecheck, and package tests
• Chat Completions and Vercel streams: valid UI, broken fenced UI, tools-then-UI
• Persist uses result.content when Autofix ran
