fix(mosaic): keep InputGroup at its size on touch devices

[alexcarpenter]

Description

On touch devices InputGroup.Root was floored at a 44px min-height, which overrode its size-based height. The private --_cl-input-group-height variable that addon buttons size from kept the original value, so buttons in InputGroup.Start/InputGroup.End stayed small inside a taller field.

This removes the coarse-pointer min-height so the group keeps its size, matching plain Input. Addon buttons still get a 44px hit area from Button's touch-target overlay, and the 16px coarse-pointer font size (which prevents iOS focus zoom) is unchanged.

📝 Walkthrough

Walkthrough

The input group root styles no longer set a minimum height for coarse-pointer devices. The targetVars import was removed. The changeset file now contains only empty YAML frontmatter.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: 🔵 Low · up to d4579

The InputGroup fix may not reach consumers until a patch changeset entry is added. The code change itself looks safe to merge.
