Fusion Agent 1936c78774 FN-194: prevent involuntary Kanban scroll from text selection
Prevent native text-selection autoscroll from competing with intentional Board panning while preserving editable controls.

- Suppress selection across Board surfaces and restore it for editable descendants.
- Document the scrolling behavior and add CSS and component coverage for responsive and grouped columns.
- Add a patch changeset for the dashboard behavior fix.

FNXC:BoardTextSelection 2026-08-27-10:06:
FN-194 keeps the intentional `useBoardMousePan` drag while removing the browser's second horizontal-scroll system: selection-autoscroll begins before its 4px pan threshold when text is dragged. The operator explicitly chose non-selectable Board text to prevent that involuntary scroll.
Anchor this at `.board`, rather than a workflow variant, so both live roots, the skeleton, every breakpoint, and every data state share the rule. The editable carve-out must remain more specific than suppression so inputs and inline card editing keep native text selection independently of CSS import order.

FNXC:BoardNavigation 2026-08-21-16:03:
FN-109 shows grab feedback only after a desktop/tablet pan crosses horizontal intent from a safe
surface or noninteractive task-card body/text. Controls, editing cards, the unbound skeleton, and
the disabled mobile path never activate it; this gesture pans the viewport and never relocates a task. Selection suppression is unconditional and owned by the BoardTextSelection rule above.
