Greptile Summary

Automated upstream sync of config/languages.yml from github-linguist/linguist, adding a handful of new language/filename entries with no logic changes.

• Blueprint language added: new markup entry with .blp extension and language_id: 765545512.
• C# color updated: #178600 → #7355dd, matching the upstream brand change.
• New filename associations: .tgitconfig and config.worktree for Git Config; .ckignore and .rgignore for Ignore List.

Confidence Score: 5/5

Safe to merge — the change is a pure data update to a static YAML config file with no executable logic.

All changes are additive data entries (a new language, new filename aliases) or a color value update, directly mirroring upstream Linguist. Nothing affects application behavior or data integrity.

No files require special attention.

Important Files Changed
