The merge branch pattern uses single quotes around the branch name but doesn't account for Git's default merge messages which use double quotes. Consider using \"Merge branch '[^']+' into [^\\s]+\" or make it more flexible to handle both quote styles.

Suggested change

	const mergeBranchPattern = "Merge branch '[^']+' into [^\\s]+";
	const mergeBranchPattern = 'Merge branch [\'"][^\'"]+[\'"] into [^\\s]+';
