Subject: [PATCH 2/3] Implement file-based error logging for all OSes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add NLog.Extensions.Logging package for cross-platform file logging
- Configure NLog with separate error and all logs files
- Add log rotation and archiving (10MB files, 7 error archives, 3 all archives)
- Update Program.cs to use NLog provider
- Add logs/ directory to .gitignore
- Ensure NLog.config is copied to output directory

Fixes #114
