Pull Request Overview

This pull request adds validation to ensure template patterns match existing files when creating a TemplateEngine. The change modifies the TemplateEngine::new method to return a Result and fail early if any template pattern doesn't match any files.

• Changed TemplateEngine::new to return Result<Self, Error> instead of Self
• Added validation logic to check template patterns against available files
• Updated all call sites to handle the new return type with proper error handling
