New virtual method on JasperFxEventProjectionBase: Task EnrichEventsAsync(TQuerySession, IReadOnlyList<IEvent>, CancellationToken) Called before individual event processing for both inline and async lifecycles. Enables batch-loading reference data to avoid N+1 queries, matching the pattern already available on aggregation projections. New IEventEnrichment<TQuerySession> interface for type-safe detection in the projection execution pipeline. Closes JasperFx/marten#4143 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

3 tests verifying event enrichment works with Polecat's EventProjection: - Simple enrichment (hardcoded property set before Apply) - Call order verification (enrichment before apply) - Database lookup enrichment (batch-load reference data) Depends on JasperFx/jasperfx#176 (EnrichEventsAsync on JasperFxEventProjectionBase) Temporary ProjectReference to local JasperFx.Events for development.
