📝 Walkthrough

Walkthrough

Two bug fixes in the diagnostic link parser: First, corrected a string interpolation error message that was missing a closing brace in the format string. Second, fixed the .md extension stripping logic in UpdateLinkUrl to calculate the removal index from newUrl instead of the original url, ensuring the suffix is removed at the correct position after earlier URL transformations.
