AgentLifecycleFactFailedEvent class

agent_lifecycle_fact_failed — emitted when the lifecycle fact mirror (FR-FBCORE-AGT-080..087) fails to write a FactRecord. Hosts listen to this to surface silent fact-write errors that would otherwise be invisible (since recordLifecycleAsFacts is best-effort by design).

Triggered from ForkEngine._store, AgentRegistry.delete, AgentRegistry.recordEvolution, and AgentRuntime.ask whenever system.facts.writeFacts(...) throws. The agent operation itself (storeOwned / delete / record / ask) still completes — the event is purely observability for diagnosing FactGraph adapter issues.
