Walkthrough

The writeSourcePlainHost function in pkg/runner/outputter.go was refactored to use strings.Builder instead of repeated string concatenation when assembling per-host source lists. Control flow and output formatting remain unchanged.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• Verify correct use of strings.Builder APIs and final trimming (TrimSuffix) on builder.String().
• Confirm identical output for edge cases (empty sources, single source, trailing delimiter).

Poem

🐰 I stitched the strings with gentle care,
A builder hummed where concat was bare,
Quiet bytes now hop and play,
Clean lines lead the carrot way! 🥕
