Subject: [PATCH] fix(core): make autoUpdateConversationModel work without rule

The trigger condition required resolved.constraint.autoUpdateModel === true,
but autoUpdateModel defaulted to undefined when no rule was configured,
so the global autoUpdateConversationModel switch never took effect.
Default it to true so the global switch works; rule autoUpdateModel/fixedModel
can still opt out per-route.

Closes #1012
