[Copilot]

Pull Request Overview

This PR fixes the handling of .d.ts (TypeScript declaration) files in the oxfmt formatter. The key change is switching from extension-based detection to path-based detection to properly recognize .d.ts files, which have a compound extension.

• Changed SourceType::from_extension() to SourceType::from_path() to correctly detect .d.ts files
• Added test coverage for .d.ts files and glob pattern exclusions
• Added multiple test fixture files to verify formatting behavior across different file types
