Refactor DocumentService and CutListService to return Result<T> instead of throwing exceptions or using out parameters. This removes all MessageBox calls from business logic. DocumentService changes: - Load() returns Result<Document> instead of Document - Save() returns Result instead of void - Validate() returns Result instead of bool with out parameter - All exceptions caught and converted to Result.Failure CutListService changes: - Pack() returns Result<SawCut.Nesting.Result> - Exceptions caught and converted to Result.Failure Benefits: - Services are now UI-agnostic (no MessageBox) - Can be unit tested without UI dependencies - Can be reused in console apps, web apps, etc. - Errors are values, not exceptions - Clear, type-safe error handling contract 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
