Pull Request Overview

This PR standardizes how collaborators are extracted by replacing the old notification.mixin.ClassCollaborators mixins with a dedicated ClassCollaborators document type across all models, updates imports accordingly, and adds migration logic to materialize collaborator records into their own collection.

• Replace builder.mixin(..., notification.mixin.ClassCollaborators, …) with builder.createDoc<ClassCollaborators<…>>(core.class.ClassCollaborators, core.space.Model, { attachedTo, fields, … }) in all model modules.
• Update imports in each module to include type ClassCollaborators and related core types.
• Extend the notification plugin—register new collaborator viewlets and update migration scripts to extract existing collaborator mixins into standalone Collaborator docs; bump version.

• The registration for TClassCollaborators was removed from builder.createModel. Without it, the ClassCollaborators document type won’t be recognized at runtime. Please re-add TClassCollaborators alongside TCollaborators.
