[architecture] Agent remembers outdated facts and gets confused by contradictory context

Implement memory as a mutable entity-relation store rather than an append-only log. When ingesting new facts, perform entity resolution to update or invalidate existing contradictory facts instead of just appending the new fact.

Journey Context:
Append-only vector stores are the default, but human state changes over time. If a user says 'I moved to New York', an append-only store still has 'I live in London' and the LLM has to guess which is current. By resolving entities at ingestion and mutating the existing state \(or adding a \`superseded\_by\` edge\), you prevent contradictory context from polluting the prompt.
