release_2.2.0

Testing

• New unit test project (BatchConvertToRVZ.Tests) with xUnit and Coverlet coverage
• Tests covering models (FileItem, GitHubRelease) and services (FileService, BugReportService, UpdateService, SharedHttpHandler)

Bug Report Improvements

• Refactored bug report payload to match the API schema (proper message, applicationName, version, environment, stackTrace fields)
• Added structured sections in bug report messages (Environment Details, Error Details, Exception Details)
• Added truncation of message (4000 chars) and stack trace (8000 chars) fields to prevent oversized requests
• Removed unused fields from SystemInfo model (BaseDirectory, TempPath, ExceptionType, ExceptionMessage, etc.)

Error Reporting

• Added automatic bug report calls across ConversionService, ExtractionService, and VerificationService when processing fails
• Added bug report calls in MainWindow for drag-and-drop errors, file add failures, and URL open errors

FileService Cleanup

• Streamlined FileService to a pure utility with no dependencies — removed Action<string> logger parameter and all wrapper methods (file operations now use System.IO directly at call sites)

Enhanced Shutdown Reliability

• Window closing logic no longer blocks when the app is already shutting down via Application.Current.Shutdown()
• Added fallback to Environment.Exit(0) if graceful shutdown fails, with a 3-second force-exit timeout

Folder Path Validation

• Input folder and verification folder validation now checks for null/empty paths and folder existence before file enumeration
• Clear error messages logged when folder paths are invalid

Verification: Include Subfolders

• New "Include subfolders" checkbox on the Verification tab — allows recursive scanning for RVZ files
• Verification file count message now indicates whether subfolders were included

UI Polish

• Added tooltips across the UI: file list labels, Select/Deselect buttons, statistic cards, extraction overlay, and output format selector
• Improved drag-and-drop tooltip hints on DataGrids

Dependencies

• SharpCompress updated from 0.47.4 to 0.48.1

Internals & Maintainability

• AssemblyInfo.cs now exposes internals to the test project (InternalsVisibleTo)
• Async naming convention: TryDeleteFile → TryDeleteFileAsync, TryDeleteDirectory → TryDeleteDirectoryAsync
• UpdateService and BugReportService methods made internal for testability
• Removed .DotSettings.user files from tracking; added to .gitignore
