0.3.0

• Tabbed Interface: The scratchpad UI has been refactored into a tabbed system, cleanly separating the Textarea and Canvas into their own distinct views. You can now easily toggle between them to keep your workspace focused.
• "Copy to Scratchpad" Integration: A new option has been added to the editor context menu. You can now select text in any Markdown note, right-click, and choose "Copy to Scratchpad" to instantly append it to your scratchpad.
• Fixes: Addresses various plugin warnings and improves overall code quality.
