fix(integrations): validate context.dev country (ISO-2); regenerate google_docs docs

- context_dev/search: reject non-2-letter country values with a clear error instead of forwarding them
- docs: regenerate google_docs.mdx so the public index-contract wording matches the updated tool descriptions (body starts at index 1)
