M-041Add Conversation Memory to the Support Agent
Description
Nebula Corp's support agent answers questions correctly but forgets everything between turns. A user asks 'What plan is Alice on?' and gets the right answer, but when they follow up with 'How much does that plan cost?' the agent has no idea what 'that plan' refers to. Implement a conversation memory system that stores past exchanges so the agent can resolve references and maintain context across turns.
