Use selection-specific caret hit testing while starting and extending mouse selections. The public caret-position API keeps its normal line ranking, but selection drags now snap below-line movement to line edges and prefer the previous line when starting in a nearby inter-line gap. Add coverage for dragging from message text, after-text space, gutters, author names, avatar-adjacent areas, and row bottoms so these inert message regions reliably start selection.
