Incorrect handling of `@formatter:off` and `@formatter:on` markers – misinterpreted as citations

[distractor]

Description

The plugin currently misinterprets @formatter:off and @formatter:on markers as citation references, which leads to a large number of warnings and severely degrades performance.

Steps to Reproduce

1. Include the following block in a Markdown file:

   <!-- @formatter:off -->
   !!! info
       Some text here.
   <!-- @formatter:on -->

2. Run the plugin.

Expected Behavior

The @formatter:off and @formatter:on comments should be ignored by the plugin and not interpreted as citations.

Actual Behavior

The plugin interprets @formatter:off as a citation reference (@formatter), which does not exist, leading to:

• Numerous warning messages about missing citations
• Significant slowdown in the processing

Suggested Solution

Introduce special handling for @formatter:off and @formatter:on to ensure they are treated as formatting directives only, not as citation markers.

OR maybe there is a nice mkdocs formatting tool I am not yet aware off. Nevertheless, whatever formatting Clion uses, is not OK, thus the requirement for @formatter:off and @formatter:on
