Module code_block_utils 

Utility functions for detecting and handling code blocks and code spans in Markdown for rumdl.

Code block detection is delegated to pulldown-cmark, which correctly implements the CommonMark specification. This handles edge cases like:

• Backtick fences with backticks in the info string (invalid per spec)
• Nested fences (longer fence contains shorter fence as content)
• Mixed fence types (tilde fence contains backticks as content)
• Indented code blocks with proper list context handling
