Describe the Bug
Any edits done by Cursor to a project rules will have the underlying model try to remove the frontmatter section. Even if Cursor is specifically directed to not touch the frontmatter part.
Steps to Reproduce
Ask Cursor to make a modification to a project rule.
Expected Behavior
Frontmatter is left untouched, unless changes are asked for. In this case, Cursor should be able to edit the frontmatter, and conflicts with the Cursor MDC enhanced editor should not occur.
