Docs overstate which Chronicle artifacts discovered before withChronicle are picked up #133

Three pages say Chronicle artifacts discovered before withChronicle are picked up: Documentation/chronicle/registration-options.md (around line 18), Documentation/tutorial/add-event-sourcing.md (around line 92) and Documentation/chronicle/reactors/index.md (around line 27). On main, a Chronicle-only class (no Arc decorator) found by discover(...) before withChronicle is registered with Arc is dropped, so it never reaches the Chronicle client. Only classes with Arc metadata, or classes discovered after withChronicle, are recorded.

Either correct the three pages to say "call withChronicle before discover(...) for Chronicle-only artifacts", or make discovery order-independent for every app (the preview activateArtifactsInScopes option from #93 already retains such classes when it is on).
