Description

This pull request implements the functionality for the Laser Pointer tool to detect and interact with hyperlinks on elements.

Previously, the laser pointer was only a visual aid and could not be used to click on anything. With these changes, a user can now open links while presenting, which improves the tool's utility and aligns with user expectations.

Changes

• Cursor Indication: When the laser pointer is active, the cursor now changes to a pointer hand when hovering over an element that has a hyperlink. It reverts to the default laser cursor when not over a link.
• Click to Open: Clicking on a linked element with the laser pointer will now open the URL in a new browser tab.
• The original functionality of drawing a trail when clicking and dragging on non-linked elements or the canvas is preserved.

How to Test

1. Create any shape (e.g., a rectangle).
2. Add a hyperlink to it (e.g., https://excalidraw.com).
3. Select the Laser Pointer tool (k).
4. Hover over the shape. The cursor should change to a pointer hand.
5. Click on the shape. The link should open in a new tab.
6. Click and drag the laser pointer on the empty canvas or on a shape without a link. It should correctly draw a red trail without opening any links.
