Pull request overview

This PR introduces meta-plugin support for categorizing files by their role in an R project, specifically adding support for vignette and test files. The changes refactor the file role system from a single role per file to multiple roles per file, enabling more flexible file categorization.

Key Changes:

• Adds new FileRole.Vignette and FileRole.Test enum values with corresponding plugin implementations
• Refactors file role handling from singular role property to plural roles array throughout the codebase
• Enhances query outputs to display role counts and use the new stringifyRLicense utility for better license formatting
