[architecture] Treating memory updates as an asynchronous side-effect rather than a core agent loop step

Make memory mutation an explicit tool/action in the agent's ReAct loop, requiring the agent to consciously decide to save\_to\_memory\(fact\) and verify success before proceeding.

Journey Context:
Developers often hook memory updates to background listeners \(e.g., 'on every message, extract and save'\). This leads to stale or incorrect state because the agent isn't aware of what it has committed to memory. If memory is a tool, the agent can reason: 'The user just told me their new API key format. I must call update\_memory to ensure I remember this.' This guarantees the agent's working context and its persistent memory remain synchronized.
