Release v7.100.0

Added

• The Screenplay UI composition skill teaches feature and module toolbars: when to put buttons on the feature instead of repeating them on each screen, the toolbar <name> syntax with item ... action <Command> and button ... slice <Slice> lines, confirm on an item or button, how the entries reach the template's toolbar slot, and how Preview/Play and Studio's feature editor handle them, with a verification step (#846).
• The Screenplay model-authoring screen workflow covers authoring a feature toolbar through MCP (toolbars member of FeatureSyntax, replacing a button to set confirm).
• The Components toolbar skill points a Screenplay author to the feature toolbar.
