fix(guardrails): keep model-visible text in the Akto text check
- document title/context, text documents and search_result stay in the text check, so no Akto backend skips them - on /v1/messages the text check reads the messages Anthropic receives, with the guardrail's skip/scan scoping applied - a client-sent "response" key can only add reply checks, never skip recording or MCP tool-call checks - a "messages" key on the Responses API can't replace its input in the text check - the recorded IP comes only from the proxy's requester_ip_address
