Add concurrent scraping example with structured output

[MagMueller]

5/10 creative test agents needed concurrency patterns but couldn't find any in the docs.

Changes

Structured output page — added a full "Scrape multiple sites concurrently" section with:

• Python: asyncio.gather + Pydantic schema (3 sites, typed products)
• TypeScript: Promise.all + Zod schema (same pattern)

llms.txt (both root + cloud) — added compact concurrency snippet so LLMs discover the pattern immediately.

The example scrapes 3 e-commerce sites for laptop prices concurrently, returning typed Product objects. Real, practical, copy-paste ready.

Summary by cubic

Added a concurrent scraping example with structured output in Python and TypeScript. Lets users run multiple client.run() sessions in parallel and return typed Product results.

• New Features
  • Structured-output docs: new “Scrape multiple sites concurrently” example (3 e-commerce sites; typed Product list).
  • Python uses asyncio.gather with pydantic; TypeScript uses Promise.all with zod.
  • Added compact concurrency snippets to docs/llms.txt and docs/cloud/llms.txt for quick discovery.

^{Written for commit 981afe4. Summary will update on new commits.}
