Context

WIP: Added new components ToolToggle and ToolToggleList

This PR introduces three new components (Toggle, ToolToggle, and ToolToggleList) using shad/cn and @radix-ui/react-toggle.

Please note this is DRAFT and does not include all functionality or final design. This PR in NOT COMPLETE.

Changes & Results

1. Toggle
   • A low-level wrapper around @radix-ui/react-toggle that uses our class-variance-authority (cva) styling.
   • Offers variant and size options (variant="tool", size="default", etc.) to match our design system.
   • Handles pressed/hover/disabled states in a reusable, composable way.
2. ToolToggle
   • A higher-level component built on Toggle for single-tool usage.
   • Displays an icon (and optional label via tooltip) for the tool.
   • For an “always on until replaced by another tool” experience, it blocks un-toggling by ignoring pressed === false attempts.
   • Integrates our Tooltip to show the tool’s label on hover.
3. ToolToggleList (Design in progress)
   • A split-button style component for tool groups (e.g. “Measurement Tools”).
   • The left side is a standard ToolToggle for the primary tool.
   • The right side is a dropdown arrow that opens a DropdownMenu listing secondary tools.
   • Selecting a secondary tool from the list replaces the primary tool’s icon/label, sets it active, and triggers onInteraction so the parent can handle the newly selected tool.
