Instance selection is now Effect-provided context.
Use these APIs:
InstanceReffor the current project context.WorkspaceReffor the current workspace id.InstanceState.context/InstanceState.directoryinside Effect services that require an instance.InstanceStoreat entry boundaries that need to load, reload, or dispose project contexts.EffectBridgefor native, plugin, or plain JavaScript callback boundaries that need to re-enter Effect with captured refs.
Do not add new ambient instance globals. Promise and callback boundaries should either stay in Effect, use EffectBridge, or pass the required context explicitly.
