- Add length/range limits to KOL variable definitions: max_length and default_value for input/textarea, min_value/max_value/default_number for number. Backend validates and normalizes; frontend renders limit inputs in KolVariableConfig and applies limits at runtime in KolDynamicForm. - Sort workspace cards by most recent prompt/package update, falling back to granted_at. Adds updated_at to KolWorkspaceCard. - Polish TemplatesView, WorkspaceView, and KOL package management UI; route create/update/publish/archive/delete toasts through i18n and expand package form copy and status labels. - Remove stale KnowledgeView.vue.patch.
