Pull Request Overview

This PR adds right-click context menu functionality for cut/copy/paste operations in text elements. The implementation provides contextual menu items based on text selection state and element editability, using the modern Clipboard API with fallback to deprecated execCommand.

• Implements a new hook useCopyPasteContextMenu that detects text selection and element editability
• Adds keyboard interaction preservation when context menu items are clicked
• Integrates copy/paste context menu into the main component provider system

Looking good, found nothing blocking a merge 👍

I wonder if we'd want these actions to be disabled instead of missing entirely, when not supported?

I was going off of the browser like experience, when you don't have a selection, then you can't cut/copy. And when you right click something not past-able it doesn't show paste disabled. Feels a bit cleaner and readable.
