[gotcha] Leaking secrets from tool responses into the LLM context or logs

Implement regex-based secret scrubbing on tool return payloads before they enter the LLM context. Redact patterns matching API keys, tokens, and passwords to prevent them from being echoed or logged.

Journey Context:
Tools often fetch external data \(e.g., GitHub issues, logs\) that accidentally contain secrets. The LLM has a great memory and might repeat these secrets in subsequent prompts, tool calls, or log them to disk. Scrubbing the output before it hits the LLM prevents the agent from becoming a secret-exfiltration vector.
