Pull request overview
Updates the repository’s Copilot contribution instructions to prevent automated formatting runs that can introduce unrelated file churn, keeping PRs focused on the intended changes.
Changes:
- Removed guidance to run
dotnet format, commit formatting-only changes, and update.git-blame-ignore-revs. - Added an explicit rule to only edit necessary files and avoid formatting changes outside the specific issue being addressed.
