Tool `web_search_advanced_exa` fetches external web content -- indirect-injection surface

· web_search_advanced_exa

Description: "Advanced search with filters, domains, dates, highlights, summaries, and subpage crawling" -- this tool pulls externally-controlled content into the agent's context window, the canonical indirect-injection vector. Even when the user supplies the URL, content at that URL can carry hostile instructions.

fix: Sandbox the fetched content: strip prompts before forwarding to the model, constrain to an allow-list of domains, and route through capframe-guard with a `domain in [...]` caveat.
