DomainEventMapper.kt had grown into a single ~280-line `when` over every
domain event type with a ~40-line flat import list ('god mapper' smell).
Split the when body by domain area into four files, each a suspend fun
returning a MapOutcome sentinel:
- SessionEventMappers.kt — session/workflow lifecycle + chat turns
- StageInferenceEventMappers.kt — stage transitions + inference lifecycle
- ToolEventMappers.kt — tool exec/assessment + review findings (+ prettyToolParams)
- LifecycleEventMappers.kt — approval/clarification/proposal/narration/artifact/model/preempt
The dispatcher chains them; MapOutcome.Emit(msg?) vs MapOutcome.Skip
preserves the null-vs-unhandled distinction (a suppressed event like
ArtifactValidating returns Emit(null), not Skip). Public entry points
(DomainEventMapper class, domainEventToServerMessage, prettyToolParams)
unchanged — no behavior change, pure maintainability. Each per-domain
import list is now local to its file. DomainEventMapperTest green.
