Improvements:

• Search: The search_memory tool description no longer asks the agent to search proactively before answering anything that may depend on earlier context. It now asks for a search before repeating investigation or when earlier decisions, fixes, commands, or results may help (#7420)
• Automatic recall: Injected memories are introduced as "Mem0 found these relevant memories from earlier work:". The old heading called them a shallow first pass and told the agent to search again with mem0_memory, a tool DeepSeek does not have (#7420)
