web_fetch returned the page body only in the text content block, while
structuredContent carried just {format, url, bytes} metadata. Clients
that show the model structuredContent instead of the content blocks
(e.g. Claude Cowork) received no page body. Include the body as
structuredContent.body so the two representations are functionally
equivalent per the MCP spec, matching the other tools.
Also adds a handler-level live check (test:live) asserting
structuredContent.body matches the text content, and bumps the version
to 0.2.2 with a changelog entry.

Summary
web_fetchreturned only the metadata line{format, url, bytes}and the page body never reached the model.contenttext block, whilestructuredContentcarried metadata only. Cowork shows the modelstructuredContentwhen present (the MCP spec expects the two representations to be functionally equivalent); standard chat usescontent, which is why it worked there and whyaccount_status/web_search/ai_chat_completion(full payload instructuredContent) worked in Cowork.structuredContent.body, matching the equivalence pattern of the other tools.test:liveverifyingstructuredContent.bodymatches the text content; version bump to 0.2.2 + changelog entry.Test plan
