v2.2.1

This patch resolves two integration issues:

• Single-body adaptive scaffolds now span non-occluding folds when no secondary body is active at the current breakpoint, including emptyBuilder overrides. Physical hinges, occluding folds, explicit secondary panes, and navigation-on-secondary layouts retain their separation. Fixes #23.
• DmChatView(showInput: false) omits the built-in composer so applications can provide their own input or companion-screen controls. Message navigation, pinned scrolling, and unread indicators remain available. The default remains showInput: true, and the option can change at runtime. Fixes #24.

All 12 packages are released as 2.2.1, with internal dependencies aligned to ^2.2.1.
