Mobile viewport lock, overscroll containment, and virtual keyboard optimizations for DeepSeek Harness (DSH) Web GUI.

Mobile Chat View	Virtual Keyboard Open	Sidebar Open

Viewport Lock: Prevents the page (html, body) from scrolling or bouncing into the empty black space below the application.
Overscroll Containment: Keeps scroll gestures inside [data-conversation-scroll] with overscroll-behavior-y: contain.
Virtual Keyboard Resizing: Configures interactive-widget=resizes-content so virtual keyboards resize the viewport cleanly instead of panning the page.
Sidebar Auto-Retraction: Automatically collapses the sidebar when tapping anywhere in the conversation area or selecting a session row on mobile.
Input Zoom Prevention: Enforces a minimum 16px font-size on text inputs for mobile viewports to prevent iOS and Android auto-zoom.

Add to your DSH web profile (~/.dsh/profiles/web/package.json):
