WHY IT NEEDS A POLICY

Why capture_successful_pattern needs a policy

This tool stores/saves data (a successful pattern) for future use across projects. It is a write operation that creates or records new data in persistent storage. It does not delete, execute code, or involve financial transactions. Misuse could lead to incorrect patterns being stored and reused across projects, causing medium-level blast radius.
