📝 Walkthrough

Walkthrough

The pull request eliminates the intermediary type MdElemRef across the codebase in favor of using MdElem directly. Changes include updating export statements, function signatures, match patterns, and trait implementations. Modules related to Markdown element trees, formatting, serialization, queries, and selectors have been refactored to remove references to MdElemRef. Several enum variants and struct implementations have been renamed or restructured accordingly. The removal of MdElemRef necessitated updates to parsing logic, conversion implementations, and test utilities while ensuring that all Markdown element processing now consistently uses the MdElem type.
