Summary

This PR fixes code-copy behavior for code blocks nested in list items.

Previously, copying a code block inside an ordered or unordered list could prepend list markers (for example, 1. or - ) to the copied text. This happened because markdown list formatting was applied during text extraction, even for code content.

This change updates the copy text extraction logic to skip markdown list marker rendering when the target is inside pre or code, so copied output is the exact code users expect.

Also included:

• Added unit tests for getCopyableText to cover:
  • code blocks inside ordered lists (no numeric prefix),
  • code blocks inside unordered lists (no dash prefix),
  • preservation of list markers for non-code list content.
